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
Error Classification
HTTP Status Code
Description / Usage
CLIENT_ERROR
400

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.
