NullPointerException with getObject

[jingyouu]

Describe the bug

I run the following code (same as the example) to fetch s3 bucket file

S3Client{region = "us-east-1"}.use{ s3 -> s3.getObject(request){ //do nothing to make sure the error is not coming from my logic } }

And it always throw the error below when I first run the application If I added a retry line to call the function again, it works as expected in the second call.
