aws cloudformation deploy 'list' object has no attribute 'split'

[Jormundir]

aws --version
aws-cli/1.11.45 Python/2.7.13 Darwin/15.6.0 botocore/1.5.8

After creating a cloudformation template, when I attempt to deploy it, I get the python error in the title:

aws cloudformation deploy --template-file _build/cloudformation.yaml --stack-name lambda

'list' object has no attribute 'split'

Can you run this command again with --debug and give me the output. That will help track it down.

Huh, with no changes, this is working today. I'm guessing something must have changed with an API response?

Just ran into this:

'list' object has no attribute 'split'

[flaub]

Some old templates use the apparently deprecated !GetAtt [resource, attribute] shorthand. Once I changed these all to !GetAtt resource.attribute, everything was OK.

[mbp]

Same experience for me with aws-cli/1.11.51 Python/2.7.9 Windows/8 botocore/1.5.14

Changing to !GetAtt resource.attribute fixed it.
