AWS Config Resource Not Found Viewing Details

Hello,

I've created a AWS Config Rule via serverless to manage IAM roles. The rule fires correctly, but when I go to view the rule details, I get a message that the resource was not found. A possible reason given is that it doesn't have permissions. Is there a way to add permissions to the config rule to view the details? I tried attaching a managed policy that has all of the aws config permissions to the lambda role created in the stack, but that doesn't work either. Any help would be appreciated.
