A potential bug in uploading assets to S3 Storage

[keshon]

Context

Studio name: EzKino.pro
Zou version: My suspicion is that any version above 0.20.8
Zou installation type: self-hosted docker

Describe the bug
While uploading any asset file (image, video etc) via post or publish inside a task, zou throws an error:
botocore.exceptions.ClientError: An error occurred (XAmzContentSHA256Mismatch) when calling the PutObject operation: The provided 'x-amz-content-sha256' header does not match what was computed. blocking the uploading.

Expected behavior
The selected files are expected to be uploaded to S3 Storage, that serves as filesystem

Screenshots
NA

Additional context
I've tested the case on a few recent versions of zou (0.20.22, 0.20.21, 0.20.20) but the problem remained. I decided to roll back to a month old versions to see if it could help, so I tried versions 0.20.6, 0.20.7 (both non available in docker repository) and was lucky to deploy version 0.20.8 that worked without any issue.
The Kitsu version in all test scenarios was 0.20.31.

According to the log, the issue is in botocore library that is being used under the hood. And surprisingly it's a very rare case (I did some googling and didn't find much - a couple of posts with similar issue).

Hi @keshon, can you retry using Zou last version? I have upgraded flask_fs2.

If the same problem occurs, can you give us the full stacktrace and do a pip list | grep botocore to get the version of botocore.
