Upload failed: x-amz-content-sha256 must be UNSIGNED-PAYLOAD, or a valid sha256 value

I have been getting lately the following issue, with uploads not being executed anymore:
```
upload failed: ./db.dump to s3://default/[REDACTED]/[REDACTED]_2025-09-04T00:00:01.dump An error occurred (InvalidArgument) when calling the PutObject operation: x-amz-content-sha256 must be UNSIGNED-PAYLOAD, or a valid sha256 value.
```

Is something incorrect on my side or is this a bug ?
