Unexpected token directly after installation

[julkue]

I've just followed the installation instructions, installed the package, then installed ChromeiQL, set t he endpoint address and received the following error:

{
  "errors": [
    {
      "message": "Syntax Error GraphQL (28:1) Unexpected <EOF>\n\n27: \n28: \n    ^\n",
      "category": "graphql",
      "locations": [
        {
          "line": 28,
          "column": 1
        }
      ]
    }
  ]
}

The Documentation Explorer is empty too. What is the reason and what can I do to solve this issue?

I already have existing classes, so I didn't create a new "Product" data class.
