Error parsing parameter '--description' when passing a url as the option value

When I try to use aws elasticbeanstalk create-application-version and try to pass a url as the --description, I get this weird validation error. Example:

Input:
aws elasticbeanstalk create-application-version --application-name my-imaginary-app --version-label="123" --description="https://example.com/foobar"
Output:
Error parsing parameter '--description': Unable to retrieve https://example.com/foobar: received non 200 status code of 404

aws-cli version:
aws-cli/1.16.165 Python/3.7.2 Linux/4.15.0-58-generic botocore/1.12.155

This is because the CLI has behavior where if a param starts with "http/https" we'll automatically fetch the contents of that file and use those contents as the value. Your workarounds are:

  1. Set the cli_follow_urlparam to false in your ~/.aws/config file.
  2. Change your description to not start with https.

FWIW this behavior is being removed entirely in AWS CLI v2.
