Terraform error EntityAlreadyExists: Role with name iam_for_lambda already exists

问题

When running the command terraform apply the following error occurred because the role already exists.

Error: Error creating IAM Role iam_for_lambda: EntityAlreadyExists: Role with name iam_for_lambda already exists.
    status code: 409, request id: 204c6c00-0b1d-4fb9-bf9c-fca48c67d669

  on main.tf line 1, in resource "aws_iam_role" "iam_for_lambda":
   1: resource "aws_iam_role" "iam_for_lambda" {

can I use conditions/tricks to check without error if the role already exists?
