API calls randomly failing

Description

Trying to deploy a small web file browser for a public bucket at https://cdn.vastuncharted.space and it seems like either bucket.List or the ObjectIterator is sometimes returning a zero-length array? This doesn't seem to happen at all on my local machine, only on the server where it is deployed, and you can eventually get any given directory to come up by refreshing, so I'm not really sure where the error lies or how to troubleshoot it.

Hi!

No error in iterator.Err()?

Best regards,
