Error: application/octet-stream is not supported

[richierg]

Describe the bug
Get error Error: application/octet-stream is not supported when trying to convert url to gif with command like:
https://asciinema.mydomain.com/a/MUmPbyFMlDiGTjzT8wVjeClcm output.gif
This seems to be related to S3 storage usage.

To Reproduce
Steps to reproduce the behavior:

1. Configure your asciinema server to store data to S3
2. Upload a cast
3. Convert the cast from the generated url to GIF with agg
4. See error

Expected behavior
The gif should be generated

Versions:

• OS: macOS 14.7 && Ubuntu 22.04
• agg: 1.4.3

Additional context
I disable S3 storage, and use local one -> works like a charm.
So the download from storage on S3 could be a lead.

Thanks for the detailed report. I'll try to get to the bottom of it.

It works by authorizing application/octet-stream in conditions, but I am not sure if it is the good method.
