I am currently using the serverless-iam-roles-per-function plugin to give each of my lambda functions their own IAM roles. But when I deploy it, it seems like it still creates a default lambdaRole that contains all the functions. I did not define iamRoleStatements or VPC in the provider section of the serverless.yml. Am I missing something? I would like to only have roles per function. Any feedback would be appreciated.
