Better error message when trying to get a project that does not exist

[seanhamlin]

e.g.

query GetProjectShort {
  projectByName(
    name: "does-not-exist"
  ) {
    id
  }
}

the result is

{
  "errors": [
    {
      "message": "Cannot read properties of undefined (reading 'id')",
      "locations": [
        {
          "line": 6,
          "column": 3
        }
      ],
      "path": [
        "projectByName"
      ]
    }
  ],
  "data": {
    "projectByName": null
  }
}

This is not a very helpful error message, and it wastes precious time from a DX perspective, as you think your GraphQL query might be wrong.

Ideal solution

Error message is something like

"The Project does-not-exist does not exist in this Lagoon"
