NodeJS (ExpressJS) Unhandled rejection TypeError: callback is not a function

javascript node.js database angular express

The correct Syntax is

        Test.addResponse(obj, (result) => {        });

it's working:

javascript node.js database angular express

Test.addResponse((obj,result) => {})

Looks like you're giving your callback as the first parameter (instead of response). It should be 2nd.

You probably wanted to do:

Test.addResponse(res, (obj,result) => {})
