Description

This problem is related with PCDEV-1310, however in this case the problem origin comes from one parameter in the postfunction "JWT - Update issue fields", and this produces one error which breaks the export 

Expected Behaviour

It will export without errors.

Actual Behaviour

There is an error in the export related with a custom field different to our custom field in the JWT postfunction. ( one screenshot is attached)

Steps

• Create a new Kanban project
•  Create a new custom field

• Name: "dropDownField"
• Type: Select List (single choice)
• Options: opt1, opt2
• In workflow / Create-->Backlog transition: Add postfunction "JWT - Update issue fields"
• Field: dropDownField
• Value type: Standard ( THIS IS VERY IMPORTANT, with others values work fine)
• Select value: opt1
• Try to export via project configurator

Workaround

To edit the workflow inside of the target instance after the import and to manually reconfigure the function to point to the correct field.
