We are migrating from cloud to on-prem Jira. We are doing a full restore into a new environment and then importing projects onto our on-prem test system. Some of our projects import without issue but a few are missing the full issues' history, activity and some custom field values (where a custom field is a drop down).
UI:
"The import was aborted because there were too many errors. Some errors are listed below. For full details about the errors please see your logs. Please note that some elements have been created. You may want to consult your logs to see what caused the errors, delete the project, and perform the import again."

How do we figure out what the exact issue is with the project from the above error?
