🐛 Bug Report: thread 'tokio-runtime-worker' panicked at src/post.rs:19:10
Describe the bug
This message pops up a fair bit on my public Redlib instance, typically doing so a lot at once (like 10 times in a row) and seemingly returns nothing to the client as NGINX marks the backend as down without my VTS module logging any error code that would cause such.
Steps to reproduce the bug
Not sure yet.
What's the expected behavior?
This error doesn't appear and Redlib either throws a normal error or returns something proper instead of not responding at all.
