Features with no schema defined error

Hi,

 

 

I have a dynamic schema workspace where I have a reader, writer and custom-built projecter.  The workspace works correctly when I read and write certain shapefiles, but other shapefiles it does not work on  - for no apparent reason. I get the below error.  I am doing everything the same, so was wondering if there are some properties of shapefiles which affect how the dynamic schema works?

Thanks Itay,

 

 

Just to add to my question - I realised that the workspace runs correctly on points and polylines, but does not work with polygons.  So it must be something to do with polygons, but what the problem is I cannot work out.

Ok I've narrowed down the problem to it relating to the geometry definition. 

 

In the "Feature Type Properties" for the writer, I initially had "Dynamic Properties" ticked.  The "Schema Sources" was set to the Reader source (ie: **\\*.shp) and the "Schema Definition" was set to Default.  With these settings I got the "Features not written - verify feature type fanout/dynamic settings" error.

 

 

However, if I untick "Dynamic Properties" and set the "Allowed Geometries" to shape_polygon, it works.  Therefore I am assuming the issue is with the writer not recognising the geometry of the input feature.  This doesn't really help me though, as I need to use the workspace on 100s of features of all different geometries.

 

 

So my question is - why does the dynamic writer recognise the geometry when I input points and polylines, but not when I input polygons??

 

 

Thanks

@aquamarine Thanks for following up and explaining what you did. Even though this was 2 years ago, I still find it very un-intuitive within FME Workbench and your answer helped me figure out why FME was creating folders but not writing any data.

Hi, you must be sure that the schema for the data you are planning to write, is in the workspace. Apparently, you built the workspace on a couple of feature types (= shapefiles) that work fine when run. Using the workspace with other shapefiles will not work, however, you can either import the schema, define the schema dynamically (see e.g. https://knowledge.safe.com/articles/1051/index.html) or migrate the schema to a feature type that works using a SchemaMapper transformer.
