Thanks everyone in advance about helping me sort this out.
I have a topic set up on FME server and have an outside system posting a simple JSON to it. I then have a subscription that is subscribed to that topic with a workspace associated to it.
I can see that it is receiving the JSON in: Resources>System>Temp>Subscriptions
When I published this workspace to the server, I subscribed it to the topic and set: Parameter to Get Topic Message: "Source JSON (JavaScript Object Notation) File or URL. I used the JSON downloaded from the temp folder to create the workspace.
At this point I can see the job starting each time the JSON is posted to the topic, but it is not getting the data to the writer.
Am I missing a parameter that needs to push the JSON from the topic to the reader correctly?
