How to resolve Error 403 Forbidden in Amazon Q

When trying to view the Deployed URL for the Amazon Q application I created, I get an Error 403 Forbidden error message. I checked the IAM role that AWS created automatically and it has the correct resource. I had AWS create a new IAM role and the same error was produced. I'm using the AWS console to create this Amazon Q app. I'm using a File Uploader Data Source and the Retriever shows Index Status Active - it looks like it properly indexed the file I uploaded.
