Troubleshooting
You are experiencing an issue
There is of course always the chance you might find the answer to your problem in this documentation. If not, please find here on how to get in touch with developers. Please describe your problem in detail and provide a minimal reproducer (e.g. scripts, required input files) as well as any log files if available.
Depending on the complexity, you might be asked to open a ticket on JIRA to track your issue. This enhances transparency and also other experts can easily join the discussion if needed. On such a ticket, please make sure to provide the full picture and pointers to resources that are needed to reproduce the issue. If it turns out that the problem is more complex/complicated, please also feel free to ask for a slot in the WP12/13 meeting to explain and discuss within a broader round of experts.
