Failed to Evaluate TCL Expression - MicrosoftTeamsConnector Error

I have a workbench that fetches data from an API and updates a Web App in ArcGIS. I am using the Teams Connector to publish update information to a relevant Teams channel. When running this workbench locally I receive no error and the message publishes successfully to Teams. The Problem: After publishing the workbench to FME Server in Cloud, I am receiving a strange error which I cannot seem to find the solution to on any article. The error and workbench are shown below. Error: Workbench: Looking forward to hearing any opinions.

Coordinate Extractor - Correct Syntax for Last Value

Hello all,I am using CoordinateExtractor to extract the start and end coordinates of line features. Most lines have only a start and end but some have an intermediate vertex. I want to extract the start and end for the list created but if I use the -1 I get no results (according to the help 0 should be start and -1 should be end)  If I open the text editor it is showing a problem with the expression  Can anyone let me know what is the correct syntax to get the end point, please?

Remove Vertices in a polyline whose azimuth offset with adjacent line segments are within a certain tolerance

Thanks to Debbi L for her help today and pointing me to:https://community.safe.com/s/question/0D54Q00008FXAFASA5/i-have-a-100-ft-line-that-curves-and-then-turns-back-into-a-straight-line-how-can-i-use-fme-to-only-gather-the-straight-line-after-the-curve-only-i-basically-want-to-cut-out-the-curve-and-only-grab-the-line-after-the-curve While this helped, I am at a loss as to how to build the rest of this in order to achieve the removal of unnecessary vertices. I was hoping Generalizer would be able to do the trick but it is mainly based upon the distance between vertices. Any help would be appreciated!😉 To expand upon this, I would want to remove the vertices in the adjacent lines segments highlighted in this image:

Remove specific vertices in a list from a polyline

Hello, How would I remove specific vertices from a feature that are stored in a list, the vertex remover only allows one vertex be removed. I have a list with: Coordinate Index - vertices_to_remove{}.vertice_indexX - vertices_to_remove{}.xY - vertices_to_remove{}.yZ - vertices_to_remove{}.z Thanks

Read CSV multi-line header to define attribute value

I am really, really new to FME and so trying to wrap my head around everything. Essentially I have a CSV that has multiple data sets one after another, split by a multi line section of header information that it not formatted the same way as the data. I'm trying to read each section of data and write it to a single database table. So for each section I need to read a specific line within the header area (Serial number and Counter Name) and then use that as one of the attributes in the writer.  Data should look like : SerialNumber, CounterName, Date, Time, Value When complete in order to write it to the table.  From the various posts I've found I think it might involve using a variable setter and variable retriever but I'm not sure how to make that work.  Any suggestions are appreciated.

Repair Invalid Polygon Geometry Type

Hello,I wish to generate a count of points within Polygons [PointOnAreaOverlayer] but I am unable to generate a count for some polygons because of fme_rejection_code: INVALID_POLYGON_GEOMETRY_TYPEThese Polygons are either Self Intersecting or Multi Polygons. I believe I need to resolve this before I can start counting points inside but Aggregator and Geometry Validator do not seem to fix the issue.Thanks.

Segmenting a polyline feature based on rolling average of fields within the feature.

I found something back in 2009, but nothing since and no solution built for this. I have Intermedite knowledge of FME.  I have a records for every 50 meters along a roadway that contains 3 fields Ride value, Rutting, and Surface condition. These 3 values make up our Condition state of our segments. I want to reverse this and build my segments based on a Rolling average for say 1 km minimum (20 records) where the average IRI = >x, Rutting = >y and SCI = >z. it would then build a polyline or group by averages. This would be a massive upgrade to our current system which involves shovels, hammers, and coffee!!! Sample graph where the red line would be my split, the roadway here groups into 2 segments.

Split Mapinfo Table into 3 equal sizes.

We have a Mapinfo file with customers and we're using this stupid third party geocoder (for now hopefully changing) and we're pretty sure it's having an issue because of the size of the table we're sending it. I was thinking maybe I could get around it by having FME split the table into 3 equal tables and then geocoding them and then combining them back together. Does anyone know of a way to do this? There's no real column info that I could export based on anything it would have to be after X rows or something similar to that. Thanks so much! 😀

I'm using the AppearanceSetter to set textures as an appearance to surfaces. The Texture Mapping Type is set to Surface Normal. The result for the walls is correct, but the roofs are wrongly oriented. Does anyone know what the right workflow is?

HTTP Caller Sending Too Many Requests (Slack Webhook)

I am running a workspace that detects changes in data between an API and Web App and applies only updates to the Web App using a change detector transformer. I am sending a notification to a Slack Webhook but instead of a single HTTP request being made, it makes 1 request for each data record updated. What I Want:"Successfully updated 70 records". What is Happening:"Successfully updated 1 records"."Successfully updated 2 records".And so on till 70... Is there a transformer that will allow me to sum the number of updated records and only send a single HTTP request to the Slack Webhook? Workbench Screenshot: Thanks!

Output data not reading as specified EPSG code

Hi all, I am generating a workspace for a client. A requirement is that output data should be in EPSG:29902. The writers have been defined to use 29902 as the output coordinate system. However, when I open the datasets in QGIS or Arc, the data is reporting as coordinate system EPSG:29903. Is there a way to correct this behaviour? Attached is a simple workbench with a creator transformer and a writer set to use 29902. But the output generated is 29903. Many thanks

Hi all, I am fairly new to FME but have a problem with an httpcaller in a loop. I cannot seem to stop the translation when all records returned. Any help would be appreciated.

I've got a HTTPCaller in a loop that retrieves data page by page (I use offset and limit). I have a tester that tests whether 'has_last_page' is true. This all seems to works ok but the translation does not stop - it just keeps repeating the last URL even though all records have been returned.

Split list of values to time periods

I'm extracting some data from a DB that stores values for time periods against a date in a comma separated list (above). I've used a cloner to create the time period for the date. Any idea how I split the csv list (presumably using an AttributeSplitter) and append the value to the desired timestamp? Any help appreciated!Thanks

XMLTemplater and braces in text

I have an issue where I have text that contains braces that are inputted into an XMLTemplater through a SubTemplate (and also through ROOT). Since I don't want the XMLTemplater to parse the text, it is referenced as @Value(text) and not {fme:get-attribute("text")}. Still I get an issue as if FME expects a function. The log tells me: "context item": undeclared variableFor this issue I prefer not to escape the braces in my text, which of course would be a workaround.

How to convert points to multiple lines considering gaps in data and spatial sequence/ order

Hi Everyone, I need your help to solve a problem. I have many no. of points that are not in order if we look at them spatially and in many places, there is a significant gap considering its distribution. I have tried Sort and then Line builder transformer in FME but the output was generated based on the layer drawing order. Another issue is line builder does not consider the gap within point distribution and connects all points to generate a single polyline. Looking for a solution to convert points to separate lines based on their spatial sequence. The attached below screenshot could make you clear about the issue I am talking about.

Is a NULL Writer the best way to cause my workbench to complete when certain conditions are met and I do not need anything written. Or is there a better way to gracefully terminate the workbench.

I am running workbench an FME Server automation that is fired from a SQL Server insert trigger for a ArcGIS feature class that has editor tracking enabled. On the workbench I check previous records for the feature and only want the workbench to complete under specific conditions - it is writing an HTML file. I was considering using the NULL writer but the documentation indicates this should only be used for testing. Looking for the best way to accomplish this. I considered modifying the trigger but this is so involved and much easier and cleaner to do in FME... Any tips would be appreciated.Thanks!

Hi All. I have a Civil 3D file that has block data that contains several attributes. When I set the parameters to explode blocks to entities all the attribute information is lost. Is there anyway to preserve the attributes?

If I do not explode, I loose the 3d surface and the geometry is shown as point.

How to download files in a folder via ftp?

Hi all,I'm trying to download files (in this case zip files), which are in a parent folder on an ftp. The folder name changes once a week, when new updates are uploaded. I would like to automaticly download the updated files once a week, but it seems that the ftp caller has some limitations in that department - (asterix and subfolders). I have searched the forum for answers, but haven't really found a solution yet. I've seen suggestions using python caller and ftp caller combined, but I dont really do python :-) Any suggestions? Thanks
