I get a 502 Bad Gateway on my VM webserver and I don't know what to do. The error message I get is the following when running pm2 log.

Based on the simple implementation of Meteor Cluster MicroServices the doc I have this implementation for 2 services to communicate.
AppUI
export default CLUSTER_DISCOVERY_URL="mongodb://localhost:3000/meteor";
Cluster.connect(CLUSTER_DISCOVERY_URL);
Cluster.register('appui_service');
loggerService = Cluster.discoverConnection('logger_service');
LoggerService
export default CLUSTER_DISCOVERY_URL="mongodb://localhost:3300/meteor";
Cluster.connect(CLUSTER_DISCOVERY_URL);
Cluster.register('logger_service');
loggerService = Cluster.discoverConnection('appui_service');
As it is, AppiUI runs on port 3000, while LoggerService is on port 3300. When I tried, started the servers, I kept on getting this error log.

I don't understand what the discovery backend means. Secondly, I want to use Meteor's default bundled Mongo for this test, not a stand-alone Mongo, what can I do to get pass this error?
**EDIT: I solved this issue.
For imports to work with Meteor, you have to put your code in an /imports/ directory. Here's the official guide on structuring your app. It's odd because I was importing and exporting most things just fine without using their recommended file structure. It was only css imports that were not working.**
Whenever a import css from an npm package, I get the following error:

The example above is when importing codemirror's css but I also get the same error with many other packages, including react-s-alert and medium-draft.
Here is my .babelrc file:
{
"plugins": [
"transform-class-properties"
],
"presets": [
"babel-preset-es2015",
"babel-preset-react",
"babel-preset-stage-2"
]
}
I am trying to setup a mysql connection in node js using bookshelf and knex. This is my setup:
var knex = require('knex')({
client: 'mysql',
connection: {
host : '127.0.0.1',
user : 'my_user',
password : 'my_password',
database : 'my_db',
charset : 'utf8'
}
});
var DB = require('bookshelf')(knex);
module.exports.DB = DB;
I get the following error:
Error: [object KnexClient] is not a valid Knex client, did you misspell it?

Looks like the line : require('bookshelf')(knex) throws an error.
I had an old version of bookshelf, I changed it in package.json from:
"bookshelf" : "0.5" to "bookshelf" : "*" and it seems to work now.
run
npm i --s mysql
it requires this package
After running grunt karma, getting below error, the only change which I made, was upgrading the node packages.

Hope to get some pointers to resolve the same.
P.S. It's been running fine if I use karma using 'karma start test/karma.conf.js' from the terminal. But I have been trying to kick off karma through grunt-karma task as well and that's where it's failing.
