The execution of template action 'For_Each_Area' failed: the result of the evaluation of 'foreach' expression '@body('Get_file_properties')?['AffectedArea']' is of type 'Null'. The result must be a valid array.
I am testing within a Condition block whether the field is empty, and this passes; yet when it then tries the For Each item in the multi-choice column it comes back with the error.
As can be seen below the field is not null and has an entry - what is happening here?
