Describe the bug

Using:

azure-cli                         2.57.0

core                              2.57.0
telemetry                          1.1.0

Dependencies:
msal                              1.26.0
azure-mgmt-resource             23.1.0b2

Created an Azure function with:

az functionapp create --name "$function_name" `
--storage-account "$storage_account_id" `
--plan "$plan_id" `
--resource-group "$resource_group" `
--functions-version "$functions_version" `
--image "$container_registry.azurecr.io/$image_name" `
--registry-password "$password" `
--registry-username "$username" `
--disable-app-insights

This command produces the warning

App settings have been redacted. Use `az webapp/logicapp/functionapp config appsettings list` to view.
App settings have been redacted. Use `az webapp/logicapp/functionapp config appsettings list` to view.

which refers to #27724 .

Once the Azure Function has been created, configuring it with

az functionapp config appsettings set `
--name $function_name --resource-group $resource_group `
--settings SOME_SETTING="some value"

produces the warning message

Runtime docker not supported for os linux. Supported runtimes for os linux are: ['dotnet-isolated', 'dotnet-isolated', 'dotnet-isolated', 'dotnet', 'node', 'node', 'node', 'node', 'python', 'python', 'python', 'python', 'python', 'java', 'java', 'java', 'java', 'powershell', 'custom']. Run 'az functionapp list-runtimes' for more details on supported runtimes.
App settings have been redacted. Use `az webapp/logicapp/functionapp config appsettings list` to view.

This appears to be a false warning message, since the container runs as expected on the Linux host. This warning message has started appearing after updating to a more modern Azure CLI version.

This would include too much personal data.

Expected behavior

Do not expect to see either warning message, since this type of deployment has worked for several years. The warning messages have only started appearing with a more recent version of the CLI.

Thanks for referencing #27724, these warning messages still break several build pipelines in our infrastructure.
