Cisco Umbrella Data Connector - Azure function invocations fail with "The specified resource type does not match the type of the existing resource"

[vamshisiram]

We are just now onboarding Cisco Umbrella data connector inside Azure Sentinel and are getting the following error on EVERY function run (so every ten mins):

The function got created fine and shows no errors. The Data Connector shows connected but only some tables are getting pulled. The proxy logs are not updating since the initial run (24 hours ago).

Azure Functions is using Python 3.11.

We reviewed the troubleshooting guide here https://github.com/Azure/Azure-Sentinel/blob/master/Solutions/CiscoUmbrella/Data%20Connectors/CiscoUmbrella_TestingInstructions.docx and the error below is not listed in that troubleshooting guide, so reaching out here in GitHub for assistance.
