Changed a table's header's name. But Flow keeps getting errors because of 'Required properties are missing from object ABC123XYZ'

The input body for trigger 'manual' of type 'Request' did not match its schema definition. Error details: 'Required properties are missing from object: ABC123XYZ.'.

This is the error I keep getting when trying to run a flow. The flow worked great, until I changed the name (cell) of a table's header. (Please note I also updated, i.e. reselected the updated header in the actual Flow)

It keeps referring to the old name "ABC123XYZ" even though this is no longer present in the header's cell, and neither in the fields of the actual Flow.

Is there a reset button or something, for Flow? Because I believe it is referring to something that was already changed.

When troubleshooting the trigger error, by looking at the BadRequest INPUTS (via There's a problem with the flow's trigger > Fix the trigger 😞

I see that, in

  "required": [


It's the only one which doesn't say _Formatted for some reasons.


But many of the others listed there in "required": [ also are no longer required, and no longer used in the actual flow.
