javascript - Error Object undefined for Express application -

i have setup express app. seems global error object undefined.

console.log(error) gives 'undefined' , , console.log(json.stringify(new error('error message')) gives {}

since error object undefined cannot return errors this

return next( new error( 'error message!' )  

is possible error object renamed or something? there work around this?

(i used intellij idea construct express app.)

any appreciated.

error object not undefined. if was, throw typeerror:

console.log(json.stringify(new error('error message'))); 

instead, returning empty object, because v8 returns if send error object json.stringify(). i'm not sure if that's feature or bug or neither, regardless, give result expect:

console.log(new error('error message'));
