S3 Express Session opened for all asyncio calls about aiobotocore HOT 4 CLOSED

Thank you for your quick feedback. I tested your 2 points:

1. Awaiting the first task before the other are executed indeed works. Let me know if I can be of any help for caching logic investigation.
2. When providing the full endpoint (my-bucket--eun1-az1--x-s3.s3express-eun1-az1.eu-north-1.amazonaws.com in my example), I get a NoSuchBucket error surprisingly.

Thank you for reporting the issue. I have a few ideas and could need your help to check them out and report back:

1. We had to implement a custom credential cache that might be to blame. Could you please try to await the first put_object task before gathering the others?

   await tasks[0]
   await asyncio.gather(*tasks[1:])

   If that helps, I will attempt to improve the caching logic.

2. According to docs for PutObject:

   When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com.

   Have you tried providing the bucket name in this format?

Great! I will prepare a fix ASAP.

Well, it was worth a shot.

@jakob-keller ah I missed that, ya it needs to use an asyncio.Lock
