Find the break with the Flow checker

A benefits FAQ flow at Contoso won't publish, and the HR team needs it back by end of day. Guessing would take hours, but Copilot Studio checks a flow every time you publish it and names the step that's wrong.

You'll build a small agent flow with the same fault, one required field left empty, then publish it and read the error the Flow checker reports. The error is the point here, so leave the field empty for now.
