amazon web services - Populating Cloudformation stack when using modules - Stack Overflow

I'm new to using the modules feature from AWS Cloudformation. I have registered the following simple IAM role fragment using the Cloudformation CLI to test things out.

ORG::IAM:Role::MODULE

AWSTemplateFormatVersion: '2010-09-09'
Description: A module wrapping a IAM Role.

Parameters:
 RoleName:
  Description: Name for the IAM role
  Type: String
 RoleDescription:
  Description: Description for the IAM role
  Type: String
 ManagedPolicyArns:
  Description: Managed policy ARNs for the IAM role
  Type: List<String>
 RolePolicy:
  Description: Policy for the IAM role
  Type: List<String>
 RoleService:
  Description: Service for the IAM role
  Type: String

Resources:
 Role:
  Type: AWS::IAM::Role
  Properties:
   AssumeRolePolicyDocument:
    Version: 2012-10-17
    Statement:
      Effect: Allow
      Principal:
        Service:
          - !Ref RoleService
      Action:
        - sts:AssumeRole
   Description: !Ref RoleDescription
   RoleName: !Ref RoleName
   Policies: !Ref RolePolicy
   ManagedPolicyArns: !Ref ManagedPolicyArns

This works as expected, but when I use this module inside a new CF template, as seen below, I get the following error:

ORG::Glue::Crawler::MODULE

AWSTemplateFormatVersion: '2010-09-09'

    Type: String
  TablePrefix:

    Type: String

      RolePolicy:
        - PolicyName: !Sub "${CrawlerName}Policy"
          PolicyDocument:
            Version: "2012-10-17"
            Statement:
              -
                Effect: "Allow"
                Action: 
                  - "s3:GetObject"
                  - "s3:PutObject"
                Resource: 
                  - !Sub 'arn:aws:s3:::${S3Target}*'
      RoleService: "glue.amazonaws"

ERROR:

CloudFormation failed to preprocess the stack: Template format error: Unresolved resource dependencies [CrawlerRoleCrawlerName, CrawlerRoleS3Target] in the Resources block of the template. Rollback requested by user.

It seems to concatenate the template resource and parameter names together and expects it as a new parameter. Any help would be greatly appreciated!
