toString does not accept array types

As of today i started getting a new error message in my pipelines -

 

(DF-FN-006 - toString does not accept array types)

 

This seems to be a recent change and I have quite a lot Mapping Dataflows which rely on these conversions. e.g toString(columnname)

 

Anyone know of a solution or workaround i can use?

 

Thanks

        That specific toString error disappeared; however same DataFlow fails with another error (below) past two days. Will contact Azure Support

         

        { "errorCode": "4501", "message": "Failed to fetch execution state: '', please retry. If the problem persists, please contact Azure Support", "failureType": "UserError", "target": "meta_Heap_json", "details": [] }
