Error constructors for JSON RPC 2.0 errors as described in the [JSON-RPC 2.0 Error Specification] (http://www.jsonrpc.org/specification#error_object)
code | message | meaning |
---|---|---|
-32700 | Parse error | Invalid JSON was received by the server. An error occurred on the server while parsing the JSON text. |
-32600 | Invalid Request | The JSON sent is not a valid Request object. |
-32601 | Method not found | The method does not exist / is not available. |
-32602 | Invalid params | Invalid method parameter(s). |
-32603 | Internal error | Internal JSON-RPC error. |
-32000 to -32099 | Server error | Reserved for implementation-defined server-errors. |
Specific errors are instances of the base constructor JsonRpcError
, which in
turn is an instance of the native JavaScript Error object.
Each error can be constructed with or without the new
keyword, for example
var err = new JsonRpcError.ParseError();
is the same as
var err = JsonRpcError.ParseError();

Import the JSON RPC 2.0 error module:
var JsonRpcError = require('json-rpc-error');
General base constructor for JSON RPC 2 errors:
new JsonRpcError(message, code[, data]);
Invalid JSON was received by the server.
new JsonRpcError.ParseError();
The JSON sent is not a valid Request object.
new JsonRpcError.InvalidRequest();
The method does not exist / is not available.
new JsonRpcError.MethodNotFound();
Invalid method parameter(s).
new JsonRpcError.InvalidParams();
Internal JSON-RPC error. The constructor can take an optional error object, in
which case the error's message
property will be passed on.
new JsonRpcError.InternalError([error]);
Reserved for implementation-defined server-errors. Provided error code must be in the range -32000 to -32099.
new JsonRpcError.ServerError(code);
