Azure Data Factory - Capture error details of a dataflow activity-CodePudding

I have a data flow and my requirement is to capture the error details into a variable when it fails and assign this variable to a parameter in the next data flow. I tried to achieve this until the second stage(With help) as below, but I'm unable to get this variable assigned to a parameter in the next data flow. The error I get is - Expression cannot be parsed

CodePudding user response：

To retrieve the dataflow error message, connect the dataflow activity upon failure to the set variable activity to store the error message using the expression:

@string(json(activity('Data flow1').error.message).Message)

Error Message:
