cannot find source field when bulk copying using script runner

[Pinaki Basu]

I am trying to bulk copy a custom field (text field) to an issue picker field. I am using the bulk copy function from the script runner. When I click on the preview button, an error message appears saying that JIRA cannot find the source field. I have entered the field number same way as shown on the screen.

Any ideas ?

Same behavior here. Solution was to press F5 and enter the same values again - there were no more error messages after the page refresh.
