The Extract_Changes method in ArcGIS API for Python fails to return any changes.

Solution de contournement

It seems to be an issue with the Python method not actually returning anything, despite the changes being identified correctly.

1. Save a copy of the file C:\path\to\conda\envs\arcgispro-py3-clone\Lib\site-packages\arcgis\features\layer.py
2. Open up the original file for editing with IDLE in ArcGIS Pro.
3. Go to Line 2241 of the layer.py file, which is where the extract_changes method comes from.
4. Instead of "return None", replace it with "return res".
5. Save the .py file as "layer".
6. Restart your IDE, and run the exact same code. The changes are now returned as desired.

Alternatively, use the extract_changes ArcGIS REST API method instead: https://developers.arcgis.com/rest/services-reference/extract-changes-feature-service-.htm
