Unexpected Import Failure

[Jero Dungog]

I had a backup file from one of my Jira Server instances, 
When I try to import a specific project from that backup file I get a Null Pointer Exception on the atlassian-jira.log file

While the import interface only shows: There was an unexpected problem processing the backup XML file <directory of imported file> : null

Does anyone have any idea on how to resolve this issue?

Hi Jero,

The error is occuring in the LexorankPreImportHandler while attempting to map the rank field values but conflicting on a missing value.

Additional details on the cause of this error as well as steps to correct the issue can be seen in the following KB article:

• Project Import of Software project fails with Unexpected import failure

Check this out and let me know if you have any questions.

Regards,
Earl
