Error while scanning for YAML file

[DorianN]

We're trying to include builds from YAML files into our Bamboo Server but get a very undeskriptive error in the process. When Bamboo scans for Specs it gets stuck in the status "Scanning in progress..." and I get a mail with a NullPointerException error. We've also checkt our atlassian-bamboo.log file but there isn't any more information about the error.

We're on Bamboo Server Version 6.10.3 build 61008
The repo is on Bitbucket Server v6.10.0
