azure-logic-apps - cannot create file in azure storage on failure of previous task: The schema definition for action with status code '200' is not valid

Question

I am saving a file to azure storage .

If the filename is numeric, it will be saved in DirectoryA, otherwise it will be saved to DirectoryB.

There is no "isNumeric()" function in powerflow, so I am casting the filename as int and if it fails, i am directing the flow to save the file to a different folder.

The issue is, for the task that saves file to azure storage, if i set it to "run on failure of previous task, i get the error:

The schema definition for action with status code '200' is not valid. The schema definitions for actions with same status code must match.

I cannot find any way around this, and would appreciate any advise or expertise.

Thank you
