@JAVIER VARA Thanks for reaching out. It looks like you are experiencing issues with the ArcGIS package installed in your Azure Function due to a recent update to the urllib3 library which is the last version that may not be compatible with the arcgis package.
One possible solution is to pin the version of urllib3 to the last working version (1.26.5) in your Azure Function. You can do this by adding the following line to your requirements.txt file:
urllib3==1.26.5
This will ensure that the version of urllib3 used in your Azure Function is the last working version.
Feel free to get back to me if you need any assistance.
