Hi, We are getting lot of errors during a project migration in Jira to another instances which uses custom feilds.

The project import fails in between with the below exception.

During import, Jira was not able to read value from this plugin which fail the import because too many error. The following error message triggered for every issue suggest all issues being imported associated with allCanComplete field however there is no feild as "allCanComplete" in our source project.

Both Source and target instance have same version of Checklist. (Checklist v3.1.13). Could you please help as it is blocking us atm.
