ElasticBeanstalk Bug.md

Not sure where else to put this, but if you're using ElasticBeanstalk .ebextension config files to download from S3 and load into your app and you're encountering an error "'NoneType' object has no attribute 'is_default' using ElasticBeanstalk files":

The endpoint deploy file in AWS Linux 2, /usr/lib/python3.7/site-packages/cfnbootstrap/endpoint_tool.py, has a bug where any S3 URLs matching this Regex will fail:

S3_WITH_BUCKET_PATTERN = r'https://([a-z0-9-\.]+)[\.-]s3(-fips)?([\.-][a-z0-9-]+){0,2}?\.amazonaws\.com(.*)$'

The fix is to make sure your S3 URLs look like https://s3.us-east-1.amazonaws.com/my-bucket-name/my-file-name.txt so they match the other regular expression, which does not fail on a bug.
