Error message contains unexpected prefix: "input: path "

[rot1024]

What happened?

Errors of a query are displayed as following even when using custom ErrorPresenter:

{
  "errors": [
    {
      "message": "input: signup existed user",
      "path": [
        "signup"
      ]
    }
  ],
  "data": {
    "signup": null
  }
}

We can see input: signup prefix.

The error returned in resolvers is a simple error: errors.New("existed users")

What did you expect?

I want to display ONLY the message part.

{
  "errors": [
    {
      "message": "existed user",
      "path": [
        "signup"
      ]
    }
  ],
  "data": {
    "signup": null
  }
}

This behavior is occurred by https://github.com/vektah/gqlparser/blob/master/gqlerror/error.go#L40 And we cannot change this error format even when using ErrorPresenter. Is that expected?

I do it in this strange way:

var re = regexp.MustCompile(`input: \w+ (.*)`)
match := re.FindStringSubmatch(e.Error())
fmt.Println(match[1])
