I have some time to have a go at this, I have the project running locally, andI have created a sponsor. I have fixed by using the sponsor website as the first param, and updated the test. I could alternatively set only_path: false on the link.
I can't push right now as I need to authenticate with github, and want to make sure it does not mess up my authentication with github at work.
