I have been using the following expression with an om premises SQL Get Rows action, to check if any rows were returned:
length(body('Get_rows_(V2)')?['value'])
Recently this seems to have stopped working and I get the error:
Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template language function 'length' expects its parameter to be an array or a string. The provided value is of type 'Null'.
Has anyone else experience this? I have been using the above for years and it has been fine.
