Extract_changes returning 'esriDataChangesResponseTypeEdits' but all edit types are empty

I have a layer being used in Survey123, which I am trying to evaluate automatically for changes to the data. I have read the extract_changes documentation and have successfully gotten the layer to tell me that changes have been made. At least that's how I'm interpreting 'responseType':'esriDataChangesResponseTypeEdits'. But then, the full response looks like this:

{'layerServerGens': [{'id': 0, 'serverGen': 48223929}], 'transportType': 'esriTransportTypeUrl', 'responseType': 'esriDataChangesResponseTypeEdits', 'edits': [{'id': 0, 'features': {'adds': [], 'updates': [], 'deletes': []}}]}

Another interesting thing to note is that the serverGen value is different on this response than when I navigate to the service's json using the parameters '?f=pjson&returnUpdate=true'.

Has anyone seen this issue before? It looks like this is common but I haven't found a solution that works yet.

----

Edited to add: I have been adding records, running the script, then deleting records and running the script again and nothing ever changes except the serverGen.

Hi @MaryGraceMcClellan

Have you checked the 'keep track of changes to the data' in your feature service settings?

It would also be very helpful to post the code you are attempting.

Cheers,

Glen
