From the web user interface, when I run GetPNG.fmw, I get
There was an Error
There was nothing to download as the workspace didn't generate any output.
Go back or start from the beginning.

When you run GetPNG form the FME web interface, what bounds values are you providing?
I have tried to publish the original workspace (connecting to sample spatiallite database), without changing the bounds. This also came up with
"There was an ErrorThere was nothing to download as the workspace didn't generate any output.
start from the beginning. "
I am using FME desktop and server 2018.1
I then replaced with my own filegdb and changed to bounds in the workbench before publishing it to fme server. This returns the same error.

Hi
@sunsilk11 I suggest you try to run the workspace from the server, perhaps there is no data that are being processed.
Hi
@ gisinnovationsb I am running workspace on same machine as spatiallite database.
@DaveAtSafe, I don't see an option to set the bounds in FME web interface (see attached).
Am I missing something here as I would have expected the sample you provided to work from FME server.
Thanks

Hi @sunsilk11,
The GetPNG workspace is set up to extract the bounds of the output PNG from the URL that called it. It is not possible to set these values when running the workspace through the FME Server web interface, and so the workspace will fail.
The URL http://myserver/fmedatastreaming/TestOGC/GetCapabilities.fmw should work in your WMS clients.

@DaveAtSafe
Thanks. I have added the WMS service to my WMS client. However the url requested when panning the map is as follows, which doesn't work.
http://myserver/fmedatastreaming/TestOGC/GetCapabilities.fmw?SERVICE=WMS&REQUEST;=GetMap&FORMAT;=image%2Fpng&TRANSPARENT;=TRUE&STYLES;=&VERSION;=1.1.1&LAYERS;=PETROLSTATION_PT&WIDTH;=672&HEIGHT;=307&SRS;=EPSG%3A27700&BBOX;=386902.94208973384%2C277072.6206946977%2C431353.0309899117%2C297379.43214165396
If I replace GetCapabilities.fmw with GetPNG in above url, then it returns an image
Hi @sunsilk11,
The GetCapabilities URL is used to get the information about the WMS service (ie. layers, bounds, coordinate system, etc.) and so won't return an image. The GetPNG URL is used to get the desired image.
The WMS client should be given the GetCapabilities URL. It will then use the capabilities information to automatically create the GetPNG urls for the images it needs.
