Problem scenario
You run an AWS SSM command. You receive "An error occurred (ValidationException) when calling the CreateDocument operation: Invalid document Amazon…" What do you do to get the command to work?
Solution
Document names cannot begin with three strings (regardless of capitalization): "aws", "amazon", or "amzn".
Change the document name to not have a string such as one of the above.
n.b. The error message, as of early 2020, is not very helpful. We hope Amazon will provide a better error message in the future.
