500 error for valid package

I’m trying to display the badge for https://github.com/g4s8/matchers-json/ project, the artifact was deployed to maven central successfully: https://search.maven.org/artifact/wtf.g4s8/matchers-json/1.0.2/jar

but when I try to open report for that project, I’m getting 500 error with stacktrace:

@sereshqua I don’t see any related PR or issues, so I’d say that “The performer didn’t provide any solution to close the job.”. The good practice to prove that the bug can’t be reproduced is a unit test.
