In resource "aws_iam_role_policy", you should place .name instead of .id for the role: aws_iam_service_linked_role.AWSServiceRoleForLexV2**.name**.

However, note that you can't modify an Amazon Lex V2 service-linked role (only the description can be updated). Check this document for more info: https://docs.aws.amazon.com/lexv2/latest/dg/using-service-linked-roles.html
