> There is a bug in the JavaScript custom exception constructor implementation.
> This thrift custom exception :
> {code}
> exception CustomError {
> 1: required ErrorCode code;
> }
> {code}
> results to a constructor which takes a single JS Object with custom
> properties :
> {code}
> const CustomError = module.exports.CustomError = class extends
> Thrift.TException {
> constructor(args) {
> super(args);
> this.name = "CustomError";
> this.code = null;
> // ...
> {code}
> We can check it in the associated TypeScript typings :
> {code}
> declare class ZaapError extends Thrift.TException {
> public code: ErrorCode;
> constructor(args?: { code: ErrorCode; });
> }
> {code}
> The generated code gives the JS object to the constructor of
> Thrift.TException.
> But the Thrift.TException constructor takes a single string argument :
> {code}
> exports.TException = TException;
> function TException(message) {
> Error.call(this);
> Error.captureStackTrace(this, this.constructor);
> this.name = this.constructor.name;
> this.message = message;
> };
> util.inherits(TException, Error);
> {code}
> Giving this custom object to the TException (instead of a string) throws
> unwanted Thrift exceptions in TBinaryProtocol.prototype.writeStringOrBinary :
> {code}
> Exception has occurred: Error: writeString called without a string/Buffer
> argument: [object Object]
> {code}
