JIRA Project configurator issue - An error occurred during the load / Load failed for reason: null

[Roy Chapman]

I have traced this issue and fixed, but recording in case it helps others.

In my case I was deleting a large project at the same time as using the Project Configurator.  Once the deletion had completed this was cleared.  We are using Data Center and tend to delete projects and run imports on the "dark node".  These can't be run in parallel.  Maybe the plugin could produce a more meaningful message in this instance?

An error occurred during the load:

[José Marañón [Awnaba Software S.L.] · Accepted solution]

That is an expected limitation of the product (but, unfortunately, not documented as this is the first report of its kind): you should not be doing other configuration changes while you are importing a configuration. The reason is that the plugin operates by comparing the intended configuration with the existing one, computing which changes must be applied to bring the second one to be like the first and, finally, applying those changes. If in the middle of this process someone else is changing the configuration it might happen (even if it is not likely) that a race condition is produced with the result of an import error.

Having said that, I estimate the exact cause of the error trace shown here is an issue type that does not exist. That does not look as a race condition with someone who is deleting a project, so it may be that simply both events happened simultaneously without a cause-effect link between them.
