'body/feature/attributes/pfr' to be of type 'String' but is of type 'Integer'.'
That's you issue right there. You likely have an incorrect variable somewhere in your flow. Without seeing your flow, i couldn't say. Any chance you can include at least a screen cap of the error in Power Automate?
I believe it's a bug. It's the same issue that from this post, but for the select one from file question type. I changed the question type to text and now the flow is working.
