This document explains about the various error responses the inQuiry micro service currently throws. The intent of this document is to look through the errors and classify it and propose any changes in terms of error reporting.

Broadly classified, there are three types of error responses that are coming out of the APIs.

Error Classification

HTTP Status Code

Description / Usage

CLIENT_ERROR

400

The client sends a bad request that resulted in service validating and throwing the error.

RESOURCE_NOT_FOUND

404

The client request for a resource that is not found in the server.

SERVER_ERROR

500

Service resulted in unexpected results while processing the client request.

Proposed Error Response

Solution 1

Recommendation is to use the error standards as specified in the http://jsonapi.org

code: an application-specific error code, expressed as a string value.

title: a short, human-readable summary of the problem that SHOULD NOT change from occurrence to occurrence of the problem, except for purposes of localization.

detail: a human-readable explanation specific to this occurrence of the problem. Like title, this field’s value can be localized.

source: an object containing references to the primary source of the error. It SHOULD include one of the following members or be omitted:

pointer : a JSON Pointer to the value in the request document that caused the error

parameter: a string indicating which URI query parameter caused the error.

header : a string indicating the name of a single request header which caused the error.

 Sample error structure
{
  "errors": [
    {
      "code":   "1000",
      "source": { "pointer": "/name" },
      "title":  "Name not set",
      "detail": "Required Metadata name not set."
    },
    {
      "code":   "1001",
      "source": { "pointer": "/code" },
      "title": "Code not set.",
      "detail": "Required Metadata code not set."
    },
    {
      "code":   "1002",
      "source": { "pointer": "/mimeType" },
      "title": "Required Metadata mimeType not set."
    }
  ]
}

We can reserve error codes for the parent category of errors, something like outlined below,

CLIENT_ERROR - 10000 to 20000

RESOURCE_NOT_FOUND - 20001 to 30000

SERVER_ERROR - 30001 to 40000

Solution 2

Preparing a key / value of the field with the error and corresponding message.

 Sample error structure
{
  "errors": {
      "name" : "Required Metadata name not set.",
      "code" : "Required Metadata code not set.",
      "mimeType" : "Required Metadata mimeType not set."
    }
}

One limitation with this approach is if there are multiple errors to be returned on the same field, then it becomes difficult.
