Test/Run trigger not working from within Azure Function under Flex Consumption pricing tier; throws CORS error

I'm an Azure novice/intermediate. Please bear with me.

I have a Function App with a collection of timer triggered functions that need to run for ~20minutes each. I decided to upgrade my Function App to the Flex Consumption plan from the lowest-tier Consumption plan so that the functions could run longer. Nothing else in my deployment parameters changed. I deploy from within VS Code.

When I triggered functions in the Consumption plan from within the portal (Test/Run), things worked as expected. After switching to the Flex Consumption plan, I get the "Please add domain to the CORS section" error when I try the same Test/Run trigger. Of course, https://portal.azure.com is already added. I have also tried with the wildcard "*".

Any ideas on how to resolve this?

    Hi @jmahmood , I understand that you have a Function App (Flex Consumption), but you got CORS error.

    After you contacted Microsoft Support, they confirmed that this feature has not yet been implemented for Flex Consumption plan, so making CORS changes did not end up helping.

    Thank you for your update.
