JSON importer fails when importing issue history

[Zan Dragan]

Hi,

We have recently upgraded our test instance to the version 7.4.2 with which a new problem arose. When trying to import projects using JSON importer we get the following error:

2017-08-04 10:45:17,076 ERROR - Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state

If we remove the history data from the JSON, the import goes through without a problem.

As for the format of history data. It hasn't been changed and the same format used to work on the version 7.0.5. From the error description I also doubt it's an issue with the format but rather with underlying code of the importer itself.

Anyone else experienced this on the version 7.4.2?

Žan

After succesfully narrowing it down with the support team, the following bug has been raised:

https://jira.atlassian.com/browse/JSWSERVER-16042

Basically JSON importer is case sensitive and expects the exact same statuses for History items.

Hi Zan,

I see you have a ticket in with Support.  Once you try the suggestion the Support Engineer provided let them know the results and let the Community know as well.

Cheers,
