`s3_get_file` error not useful when incorrect `region` is used

[a-cakir]

Running

s3_get_file(AWS.AWSConfig(;profile="xxx",region="eu-central-1"),bucket, prefix, filename)

works as intended, however if one changes the region from eu-central-1 to say us-east-1, then running the same code leads to the (not so useful) error below,

s3_get_file(AWS.AWSConfig(;profile="profile",region="us-east-1"),bucket, prefix, filename)
