Hi @Sudharsan_Ka ,
I see you are ending with a Throw, this means that normal arguments do not normally work within that Try Catch.
If you want to pass out info to the Main workflow, coming from an error in the try, you need to 1st init a DataTable or a Dictionary in the main. Set it as In/Out inside the Process.xaml, and then fill it inside.
Normal “String Out arguments” do not carry information out of the TryCatch.
Please try it and update us!
Best Regards,
Ignasi
