Invalid Bucket name when creating s3 bucket with AWS SDK

It's all about name convention!

The bucket name can be between 3 and 63 characters long, and can contain only lower-case characters, numbers, periods, and dashes.

AWS provides naming standards when naming an aws bucket.

• The bucket name can be between 3 and 63 characters long, and can contain only lower-case characters, numbers, periods, and dashes.

• Each label in the bucket name must start with a lowercase letter or number.

• The bucket name cannot contain underscores, end with a dash, have consecutive periods, or use dashes adjacent to periods.

• The bucket name cannot be formatted as an IP address (198.51.100.24).

The name provided contains upper case letters, by switching to lower case letters the issue can be resolved.
