Deployment Failed: Deploy From Bitbucket Using AWS CodeDeploy

Question

I was able link bitbucket with aws although the deployment from bitbucket returns an error below.

Deployment Failed
The deployment failed because no IAM role with the IAM role name (arn:aws:iam::******:role/m30role) specified in this request was found. Make sure you are using the correct name of a service role that exists in your account. (Error code: IAM_ROLE_MISSING) Learn more

Any idea about this? Or which part of aws should I check

Any recommendation for a good tutorial on setting up Deploy From Bitbucket Using AWS CodeDeploy.

Builds from bitbucket (Deploy to AWS) were uploaded to s3 buckets and I was able to see all the deployments history but then again all builds were failed.
