ISSUE:
There exists a bucket named XYZ in either Amazon S3 or Google Cloud Platform, and you receive an error message on either the Origin or Destination for those components which states:
Error: Invalid bucket name
SOLUTION:
You may have also specified a subdirectory as well as the bucket name.
In the Bucket input field, you need to pass only the bucket name and in the Common Prefix input field, you need to pass the name of the subdirectories or path depending on how you are reading or dropping the file. You can see the example in the attached print screen.
