`An error occurred`... error


I´m using a self-hosted Docker GitLab instance on my vServer (8 vCPUs, 32 GB RAM) and I get the error message from the screenshot below in random intervals.

The error is covered by an infinitive loading and after a refresh of the page, the issue is gone.

Suggest correlating the error timestamp to the logs, and look for 500 error codes in the production log.

Additionally, the browser dev console might shed some light, according to this comment: "An error occurred while loading the blob controls." - #2 by cgola

The topic also links to Cannot download over 4GiB LFS files form the UI (#364455) · Issues · GitLab.org / GitLab · GitLab which has been resolved with this MR Use BigInt for Graphql Blob type to cover huge files (!106047) · Merge requests · GitLab.org / GitLab · GitLab in 15.7. Depending on your GitLab version, I’d suggest trying to upgrade to the latest 15.9.x release (or wait until 15.10 is released tomorrow on the 22nd).
