Random 'Unknown error' thrown by Uppy

Hi all,

I can’t get a local reproduction of this problem so I didn’t want to create a bug request but I’m really struggling with an “Unknown error” that gets thrown by Uppy. I’d say it’s working well 99% of the time but we are occasionally getting reports of uploads failing and I can see them in our logs.

Looking at the codebase there are only two instances where a “Unknown error” string gets used:
https://github.com/search?q=repo%3Atransloadit%2Fuppy%20"unknown%20error"&type=code

We are using the aws-s3 package (v3.6.2).

Attached is a screengrab of the logs I do have but does anyone have any hints or ideas about how I can try to debug this further?

The calls to upload to AWS all seem to continue in the background but the UI shows
“Failed to upload” and never recovers.

Hi, sorry to hear that. Unfortunately without a way to reproduce it’s hard for us to take a look.

@iblack10 did you ever figure out what could be happening here? I’m running into the same issue when uploading 100 or so 10-20 MB files. I am able to successfully recreate this pretty consistently if that could be helpful in diagnosing.

I haven’t been able to resolve the issue. I was never able to get recreate it myself and only had some logs and user reports to go on. If you can provide the Uppy team with a reproducible example that could definitely help them investigate!
