generic throw giving Expected an object to be thrown lint error

javascript ecmascript-6 polymer eslint throw

 throw Object.assign(   new Error(myMessage),   { code: 402 });

Throw a regular error and extend it with custom fields.

You could also write a reusable error class for that:

  class CodeError extends Error {   constructor(message, code) {    super(message);    this.code = code;   } } throw new CodeError(myMessage, 404);

That way, you can distinguish the errors easily on catching:

  } catch(error) {    if(error instanceof CodeError) {      console.log(error.code);    } else {      //...    } }

Another simple workaround is store on variable and throw.

const errorMessage =  { code : 403, message : myMessage };throw errorMessage;
