module.exports = {
  friendlyName: 'Total',

  description: 'Total finance.',

  inputs: {
    project: {
      type: 'string',
      required: true
    }
  },

  exits: {},

  fn: async function({ project }, exits) {
    const listTotalFinances = await Finance.sum('value').where({
      project
    });
    if (listTotalFinances) {
      return exits.success(listTotalFinances);
    }

@mkbrdigital Thanks for posting! We'll take a look as soon as possible.

In the mean time, there are a few ways you can help speed things along:

• look for a workaround. (Even if it's just temporary, sharing your solution can save someone else a lot of time and effort.)
• tell us why this issue is important to you and your team. What are you trying to accomplish? (Submissions with a little bit of human context tend to be easier to understand and faster to resolve.)
• make sure you've provided clear instructions on how to reproduce the bug from a clean install.
• double-check that you've provided all of the requested version and dependency information. (Some of this info might seem irrelevant at first, like which database adapter you're using, but we ask that you include it anyway. Oftentimes an issue is caused by a confluence of unexpected factors, and it can save everybody a ton of time to know all the details up front.)
• read the code of conduct.
• if appropriate, ask your business to sponsor your issue. (Open source is our passion, and our core maintainers volunteer many of their nights and weekends working on Sails. But you only get so many nights and weekends in life, and stuff gets done a lot faster when you can work on it during normal daylight hours.)
• let us know if you are using a 3rd party plugin; whether that's a database adapter, a non-standard view engine, or any other dependency maintained by someone other than our core team. (Besides the name of the 3rd party package, it helps to include the exact version you're using. If you're unsure, check out this list of all the core packages we maintain.)

Hey @mkbrdigital , which version of Sails, Mongo, and the sails-mongo adapter are you using for this one?

This may be more related to the Mongo side as well. Have you tried adding {cursor:{}} to you aggregation pipeline? Experiences can still vary based on which version of Mongo is being used as well.

using mongo atlas, i could not replicate this issue with a fresh installation of a sails app, though i faked my data, the request did not complete, it timed-out ERR_EMPTY_RESPONSE , maybe this may be related with the driver of just an internal bug with .sum()

Hi, @navicstein! Which version of sails-mongo are you using?

[Tarrask]

this issue look like the issue #4557.

The master version of sails-mongo fix it, but it is not yet published on npm.
