ERROR Variable "$testSlug" of required type "String!" was not provided

While trying to follow the getting started guide I saw this error on the VSCode terminal. It did not broke the test or the UI but it appeared after the first npm run test:open

ERROR  Variable "$testSlug" of required type "String!" was not provided.
{
 "message": "Variable \"$testSlug\" of required type \"String!\" was not provided.",
 "locations": [
   {
     "line": 1,
     "column": 39
   }
 ],
 "extensions": {
   "code": "INTERNAL_SERVER_ERROR"
 }
}

Probably a missing check in the UI

What was the URL in the browser?
