Reacting to Azure Function failure in Logic App

Question

I have a simple logic app running an Azure Function on a recurrence trigger (every day). I want to send the IT department an email if there is a problem running the Function. Here's my Logic App setup:

However, whenever there is an error (for exemple, the azure function returns an HTTP code 500, like so:)

return req.CreateResponse(HttpStatusCode.InternalServerError, new
        {
            error = $"{errorMessage}. {ex.Message}"
        });

the Logic App flow just stops before I can check the status code an react to it:

So my question is: is there a way to handle an Azure Function error response code?

The reason for this failure is that by default the Logic App Condition is executed only on the success of the previous step.

You can override this behavior by updating the "runAfter" condition to include "Failed" state.

Go to the code view and add update your definition of error condition in json to have

                "runAfter": {
                "HTTP": [
                    "Failed",
                    "Succeeded"
                ]
