Cant export report to xlsx

Created May 26, 2023 14:25
When trying to export report to XLSX the downloaded file is broken and cannot be opened with excel. Export to CSV works fine. I checked nohup.out, but cannot find anything useful, it looks like the log is a little bit cut, because there are lines like "...110 more".
There is log that I get.

Hello,

Thank you for reaching out. Please install the fontconfig package on the machine where Youtrack runs (you can read more about this package here: https://launchpad.net/ubuntu/+source/fontconfig). It should fix the issue. If the problem persists after that, share the fresh logs again.

I have installed it, but the problem persists with the same errors. Do I need to restart my youtrack instance?

Yes, please try restarting your YouTrack at first.

The error you shared is almost always caused by the absence of the package I mentioned. Please provide the following:
1. Your OS
2. YouTrack version that you use
3. Installation type (docker, zip, msi). If you use Docker, please share a link to the respective image on Docker Hub.
4. Let us know how you installed the package
5. Share the fresh logs with the error.

I'm looking forward to your reply.
