Change Group failed to export

Issue Summary

While migrating JSM project using JSM-JCMA custom JAR, "Change group" associated with Issues fail to export.

This usually occurs when

1. Issue at some point was dis-associated from a "Request Type"
2. Issue is referencing a "Customer Organisation" that isn't associated with the project being migrated

Steps to Reproduce

WIP

Expected Results

Change group should be exported

Actual Results

The below types of exceptions is thrown in the JCMA error log file:

2021-09-19 11:40:31.369 ERROR DESK project-export We couldn't export Change Group 963XXX (on Issue XXXX-19). Reason: java.lang.NullPointerException: fieldData.changeItem.to must not be null.

2021-XX-XX XX:59:56.437066 ERROR XXXX project-export We couldn't export Change Group 43703 (on Issue XXX-255). Reason: java.lang.IllegalStateException: Entity mri:mig:jira/servicedesk:customerOrganization:4 is expected to be exported, but it was not.

Workaround

We have patched this fix in JSM-JCMA custom JAR v28, this version hasn't been shared to all via the EAP dropbox link. This will soon be done.

If you're blocked due to this export issue only, then reach out to internal teams and use v28 for the interim period.

The next release of JSM-JCMA custom JAR will have the fix for such issues. The release is expected to be made around mid Oct'21
