[BUG] AttributeError: module 'azure.functions._abc' has no attribute 'SqlRow'

I think #1029 might need to be re-opened.

• Timestamp: 2022-06-16 -> 2022-06-17
• Function App name: anomalyScoring
• Function name(s) (as appropriate): there is only one on that function app
• Core Tools version: 4?

Repro steps

Provide the steps required to reproduce the problem:

Have a perfectly good, deployed function. It starts failing after no changes from us with the error:

Result: Failure Exception: AttributeError: module 'azure.functions._abc' has no attribute 'SqlRow'

Known workarounds

Provide a description of any known workarounds.

Redeploying resolved the issue.

azure-functions

Seems exactly like #1029. The first time my production service went down because of this I was annoyed. But mistakes happen. The fact that we are getting this exact same issue again is pretty unacceptable. I know the guidance is:

# DO NOT include azure-functions-worker in this file
# The Python Worker is managed by Azure Functions platform
# Manually managing azure-functions-worker may cause unexpected issues

but I would like to know how I can lock onto a functioning version of the worker so yall can’t keep breaking my production workloads.

@lamym, no typo. We initially downgraded to azure-functions==1.11.0 as suggested by @CoAct-Atif as a workaround to our function suddenly beginning to fail out of the blue. See thread further up for details.

After implementing @MagnusWagner-WIT’s suggestion to set PYTHON_ISOLATE_WORKER_DEPENDENCIES to 1 in the Azure AppSettings, we were able to roll back the previous workaround.

@BSickmillerArchaea - Can you please share the function name? https://github.com/Azure/azure-functions-host/wiki/Sharing-Your-Function-App-name-privately for us to investigate?
