java.lang.NullPointerException at ProjectMetrics

[JonathanMeer]

Hi all,

I do not see the projects anymore and also not the components.

In the browser I see the following error when opening the projects page:

• Api call: /api/v1/project?excludeInactive=true&searchText=&sortOrder=asc&pageSize=10&pageNumber=1
• Response: (was java.lang.NullPointerException) (through reference chain: org.datanucleus.store.rdbms.query.ForwardQueryResult[0]->org.dependencytrack.model.Project["metrics"]->org.dependencytrack.model.ProjectMetrics["policyViolationsFail"])

After a restart of the apiserver it is executing metrics updates and is throwing the following error again and again (in the logs):
ERROR [MetricsUpdateTask] An unexpected error occurred while updating portfolio metrics and iterating through projects. The error occurred while updating metrics for project: 12e6cba0-65f6-4779-a138-2babfc566321

Does anyone have ever had such an issue?
Could anyone support/help me?

If more information is needed, just let me know!

Thanks in advance
Johnny

I have found an issue that explains how the error occurred. #995

Now, can someone help me fix the error without losing data?
