Error Messages in server now show as "Exception while invoking method 'methodName' [object Object]" since upgrading to 1.7


#1

Hi everyone,

Since upgrading to Meteor 1.7 my error messages on the server side have been unreadable. This has made it incredibly hard to debug server-side methods.

Examples:

Exception while invoking method 'forms/review/generate_pdf' [object Object]
Exception while invoking method 'forms/updateByProgram' [object Object]
Exception while invoking method 'forms/createForm' [object Object]

Does anyone know how to fix this? It’s really hampering any ability to write code!

Cheers!

Check your browser console to see the complete error


#3

In the browser it just returns 500 server error; not the full value of the error


#4

Try adding this inside Meteor.startup() in your server

const originalMeteorDebug = Meteor._debug;
Meteor._debug = (message, stack) => {
    if (Meteor.isDevelopment) {
        console.log('===== message =====', message);
        console.log('===== stack =====', stack);
    }

    return originalMeteorDebug.apply(this, arguments);
};

@rjdavid Does not work!
The stack received is [object Object].

Created an issue: https://github.com/meteor/meteor/issues/10078

Thanks for this @rjdavid! I had to slightly modify your answer to get the log working with this. What I did was import util to unfurl the stack object and then fix it.

import util from 'util';

const originalMeteorDebug = Meteor._debug;
  Meteor._debug = (message, stack) => {
    if (Meteor.isDevelopment) {
      console.log('===== message =====', message);
      console.log('===== stack =====', stack);
      console.log(util.inspect(stack, false, null))

    }
    return originalMeteorDebug.apply(this, arguments);
  };

@s7dhansh - tell us if this works for you!

@MDG - hope this isn’t a permanent thing! It’s a huge thing not being able to debug server issues without a workaround.

Yes it does. Thank you!
