Answer 1

When you're creating or deploying a stack you need to explicitly allow creation of IAM resources. To do that, you need to add the parameter when calling sam deploy:

--capabilities CAPABILITY_IAM

If you want to create named IAM resources (e.g. roles or users where you explicitly specify the name), you'll want to use --capabilities CAPABILITY_NAMED_IAM instead.

You can read more about deploying IAM resources in CloudFormation here: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html#using-iam-capabilities

SAM deployment documentation: https://github.com/awslabs/aws-sam-cli/blob/develop/docs/deploying_serverless_applications.rst#deploying-your-application

thanks its work fine with --capabilities CAPABILITY_IAM flag – Hamnet

thanks Could SAM be anymore opiniated ;( – Relate

Ok, 'funny' this didn't work for me: sam deploy --config-env default --profile myprofile –-capabilities CAPABILITY_IAM But this did: sam deploy --config-env default --capabilities CAPABILITY_IAM --profile myprofile – Lamebrain

Answer 2

Do check your YAML file indentation. review the YAML file once again, if it's a tad bit not up to the SAM standards it will throw this error. DO check once again.

Search the stack in cloudformation and delete it, and then try to run the command again, this helped me solve the problem
