Debug Output/Panic Output

Error: updating Monitor Diagnostics Setting "frontdoor-diag" for Resource "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/my-resource-group/providers/Microsoft.Cdn/profiles/my-frontdoor-name": diagnosticsettings.DiagnosticSettingsClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error.

Expected Behaviour

No error

Actual Behaviour

After upgrading azurerm from 3.39.1 to 3.40.0 we get the following error during terraform apply:

Error: updating Monitor Diagnostics Setting "frontdoor-diag" for Resource "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/my-resource-group/providers/Microsoft.Cdn/profiles/my-frontdoor-name": diagnosticsettings.DiagnosticSettingsClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadRequest" Message="Detected duplicated Log settings 'FrontdoorAccessLog | FrontdoorWebApplicationFirewallLog | FrontDoorHealthProbeLog | FrontDoorAccessLog | FrontDoorWebApplicationFirewallLog'."

Now we rolled back to 3.39.1 and the deployment runs without errors.
