Lambda deployment failing due to roleRole too long after updating to serverless 1.42.0

[erickpires]

This is a Bug Report

Description

Recently I updated from serverless version 1.38.x to the latest version (1.44.1) and the deployment of some of my lambdas stopped working due to the name of the roleName length been greater than 64. After some investigation I was able to conclude that the error started happening on version 1.42.0.

• What went wrong?
  The name of the roleName is built using the template {service}-{stage}-{lambdaName}-{region}-lambdaRole. On version 1.41.1, if this name is longer than 64 characters the roleName is been generated without the last part (i.e. -lambdaRole), which is an interesting behavior since this suffix is 11 characters long.
  On version 1.42.0 the behavior changed and the suffix is always been added. This made some roleNames that previously had 54 characters jump to 65 characters and now I am not able to deploy my stack anymore unless I rename some of my lambdas or my project.

• What did you expect should have happened?
  Either the old behavior of selectively removing the suffix lambdaRole should be maintained or there should be a way of specifying the lambda role name.

• What was the config you used?
  The lambda role is been generated from iamRoleStatements that are specified per lambda.
  The service has 12 characters. The stage has 9 characters. The lambdaName has 21 characters. And the region is us-east-1.

• What stacktrace or error message from your provider did you see?
  An error occurred: "..."IamRoleLambdaExecution - 1 validation error detected: Value '"..."-lambdaRole' at 'roleName' failed to satisfy constraint: Member must have length less than or equal to 64 (Service: AmazonIdentityManagement; Status Code: 400; Error Code: ValidationError; Request ID: "...").

Have you ever found a workaround to this?

Have you ever found a workaround to this?

None. For the time being I'm using version 1.41.1 and hoping I don't need any of the newer features.

I can see this behavior with version 1.41.1 too.

Error occurring on v1.50.1 as well.

same in 1.49.0
is that any options to override the roleName?

[danielo515]

This is clearly a feature regression. Adding 11 extra useless characters when there is so tight length constrains is not acceptable.
