When I do something like:
ec2_client.describe_images(ImageIds=['ami-123456'])
The response I get is missing the 'Tags'. This is not the case when I do the same call using aws cli:
aws ec2 describe-images --image-ids ami-123456
FYI: The problem is caused by the fact that credentials from another account was used due to our setup with parent and child accounts
botocore - Tags are missing from 'describe_images' response
