jamie jamison (Jan 26 2026 at 23:06): jamie jamison (Jan 26 2026 at 23:06):This is a wierd one. What it looks like is that using the backbutton gets:
Internal Server Error - An unexpected error was encountered, no more information is available.
It is completely intermittant and the server seems to actually be up.
[!IMPORTANT] Since this error is blocking the dataset.xhtml view, the page will likely continue to throw a 500 error for users until the S3 client can successfully initialize, even if the files themselves aren't being downloaded at that exact moment.
In the log I found:
