I have the error message saying: “Unable to find a constructor to use for type System.Data.DataRow. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute. Path ‘Output.out_WIList.$values[0].RowError’, line 1, position 5762.”
This happens when I extract the Data table and assign it to System.Data.DataRow. Have you ever experienced this issue? Can you advise please?
I faced the same exception! when I am assigning a datarow array variable to another datarow array argument. jsonConstructor attribute. Path ‘Output.out_WIList.$values[0].RowError’, line 1, position 143.
If you will run that workflow by invoking then it will work and if you will try to run directly then it will give the exception after running all activities.
Let me say all that I know about this exception. Isolated Invocation:
All the output arguments should be Serializable one. Arguments that aren’t Serializable like BrowserElement will throw this expection Not Isolated:
One can use Non-Serializable arguments, however the workflow will throw the same Exception if run independently i.e you just run this workflow alone. Will NOT throw Exception if invoked elsewhere
