Following a consultation with Azure Support, the integration of the subsequent parameter into my resource configuration effectively addressed the issue:

WEBSITE_WEBDEPLOY_USE_SCM = “true”

We have been experiencing this issue since the start of November.

Switching from this task to Azure CLI seems to have fixed our deployment timing out after 60 mins to <1 minute. No changes to the Function App.

- task: AzureCLI@2
    inputs:
      azureSubscription: "${{ parameters.AzureSubscription }}"
      scriptType: "pscore"
      scriptLocation: "inlineScript"
      inlineScript: |
        az functionapp deployment source config-zip --src "$(Pipeline.Workspace)/artifacts/package.zip" --name "${{ parameters.FunctionAppName }}" --resource-group "${{ parameters.ResourceGroupName }}" --slot "staging"

If possible, can you enable the debug logs (systm.debug=true) and share the logs please? Thanks

Having the same error too. All my Azure DevOps / Azure stack is impacted because of this bug I could not deploy. Thanks for your help.

Exactly the same error since yesterday
