fix(Grok): Error handling from GrokAI API

[joolab]

What:

• Bug Fix
• New Feature

Description:

GrokAI API returns an error as a string, rather than as an object, as the original OpenAI API does. I propose this adjustment to make the library compatible with the GrokAI API.

Do you have a sample of the payload structure or doc link? I haven't used Grok at all yet.

They claim that their API is fully compatible with the OpenAI REST API.

Do you have a sample response? What you've changed is like the root level parsing of a response into JSON to make that a string which doesn't seem right. I imagine its still JSON, but with a string on error?

The sample will help

GrokAI:
{"code":"400","error":"Bad data: Messages cannot be empty"}

OpenAI:

{
  "error": {
    "message": "Invalid 'messages': empty array. Expected an array with minimum length 1, but got an empty array instead.",
    "type": "invalid_request_error",
    "param": "messages",
    "code": "empty_array"
  }
}

Okay thanks. So we can probably look for code and error at root and detect this as an error. With a change like that and a change to our test suite - we could merge this.
