Error Code

In the REST API protocol, HTTP and JSON-RPC are used, so you can use the status codes of both layers. This document describes handling errors in different layers and lists examples for major errors.

Overview

• The error code is defined between 0-65535. The error code is divided into two areas (REST API system area and user area).

error code	area
0 - 32767	REST API system area
32768 - 65535	user area

• The user area is divided between the common area and each service.

error code	area
32768 - 39999	Unused areas.
40000 - 40199	Service common areas.
40200 - 40399	System service area.
40400 - 40599	Camera service area.
40600 - 40799	videoScreen service area.
40800 - 40999	Audio service area.
41000 - 41199	avContent service area.
41200 - 41399	Recording service area.
41400 - 41599	appControl service area.
41600 - 41799	Browser service area.
42000 - 42199	accessControl service.
42200 - 42399	contentDownload service.
42400 - 42599	Encryption service.
42600 - 42799	contentSync service.
42800 - 42999	contentSync service.
43000 - 65535	A reserved area.

HTTP Major Error Codes in REST API.

This is the basic policy.

• Should follow the original HTTP definition.
• Should not map others to HTTP errors forcibly.

If the HTTP status code is anything other than 200 OK. and if the HTTP server returns a response body in accordance with the REST API protocol, the error code must be same as the HTTP error code. Major error codes are listed as follows.

code	Reason phrase example	JSON example	Explanation
401	Unauthorized	“error”: [401, “Unauthorized”]	Request requires user authentication.
403	Forbidden	“error”: [403, “Forbidden”]	Server understood the request, but is refusing to fulfill it. The client does not have permission to access.
404	Not Found	“error”: [404, “Not Found”]	For cases where the request is not matched to any supported API version.
413	Request Entity Too Large	“error”: [413, “Request Entity Too Large”]	The accepted body size of the client request exceeds the maximum limit.
414	Request-URI Too Long	“error”: [414, “Request-URI Too Long”]	The accepted URI length of the client request exceeds the maximum limit.
501	Not Implemented	“error”: [501, “Not Implemented”]	When the request method is not implemented on the server.
503	Service Unavailable	“error”: [503, “Service Unavailable”]	When the server is in a temporarily unavailable state which may occur due to other concurrent connections. (The number of maximum connections is not defined because it depends on the server.)

System Error Code

1	Any	“error”: [1, “Any”]	A generic error code which can be used with any error.
2	Timeout	“error”: [2, “Timeout”]	For cases when the server cannot reply in time.
3	Illegal Argument	“error”: [3, “Illegal Argument”]	For cases when the “params” value in the request does not follow API specifications.
5	Illegal Request	“error”: [5, “Illegal Request”]	For cases when the request body is empty, has no ID or has an invalid ID, has no method, has no params, or the params is not an array.
7	Illegal State	“error”: [7, “Illegal State”]	For cases when the server cannot handle the request at this time.
12	No Such Method	“error”: [12, “No Such Method”]	For cases when the requested API does not exist.
14	Unsupported Version	“error”: [14, “Unsupported Version”]	For cases when the requested version is not supported on the specified service.
15	Unsupported Operation	“error”: [15, “Unsupported Operation”]	For cases when the server cannot handle the request with respect to the specified parameters.

40006	Please contact the inquiry counter	“error”: [40006, “Exxxx”]	A common error code used among services to be used for general errors.
