Error Activity type 'VisualBasicValue`1' requires compilation in order to run


I’m having this error when trying to filter a datatable using LINQ:

“Assign: Expression Activity type ‘VisualBasicValue`1’ requires compilation in order to run. Please ensure that the workflow has been compiled.”

How can I fix this ?

can you try:
g.First()).CopyToDataTable - we added () after First

EDITED: yes agree to @Yoichi and take his suggested hint as the first action

This error is caused by double quote except 0x22 (") For now, can you replace (reinput) double quote with " ?

The following also helps you.

Thank you. That’s really weird. I saw same problem reported by other users and this solution woudn’t help me. But now, strangely, I’ve simply copied and paste the " and it worked.
Thanks !!
