FAILED. Reason: Requires capabilities : [CAPABILITY_IAM] – AWS SAM

Hi everyone,

I ran into an error today while trying to deploy using AWS SAM:

aws cloudformation deploy –template-file C:\Users\xxx\serverless-output.yaml –stack-name events-app
Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: Requires capabilities : [CAPABILITY_IAM]

The solution is pretty straightforward. You need to explicitly add –capabilities CAPABILITY_IAM to you command:

aws cloudformation deploy --template-file C:\Users\xxx\serverless-output.yaml --stack-name events-app --capabilities CAPABILITY_IAM>

Thanks to Bfreis for his comment on this github issue: https://github.com/awslabs/serverless-application-model/issues/51
