APIError message fields may be a array

[alariczq]

{
  "error": {
    "message": [
      "Invalid schema for function 'xxx': In context=(), object schema missing properties"
    ],
    "type": "invalid_request_error",
    "param": null,
    "code": null
  }
}

Basically, it is a string. However, if the json schema of the parameters field is invalid, as shown below, it is likely to be an array.

$ curl https://api.openai.com/v1/chat/completions -u :$OPENAI_API_KEY -H 'Content-Type: application/json' -d '{
  "model": "gpt-3.5-turbo-0613",
  "messages": [
    {"role": "user", "content": "What is the weather like in Boston?"}
  ],
  "functions": [
    {
      "name": "get_current_weather",
      "parameters": {
        "type": "object"
      }
    }
  ]
}'

{
  "error":{
     "message":[
        "Invalid schema for function 'get_current_weather': In context=(), object schema missing properties"
     ],
     "type":"invalid_request_error",
     "param":null,
     "code":null
  }
}

FYI: I requested multiple functions with invalid parameters to try it out. There is only one error in the array.

$ curl https://api.openai.com/v1/chat/completions -u :$OPENAI_API_KEY -H 'Content-Type: application/json' -d '{
  "model": "gpt-3.5-turbo-0613",

  "functions": [
    {
      "name": "get_current_weather",
      "parameters": {
        "type": "object"
      }
    },
    {
      "name": "get_current_weather2",
      "parameters": {
        "type": "object"
      }
    },
    {
      "name": "get_current_weather3",
      "parameters": {
        "type": "object"
      }
    }
  ]
}'

{
  "error": {
    "message": [
      "Invalid schema for function 'get_current_weather': In context=(), object schema missing properties"
    ],
    "type": "invalid_request_error",

  }
