Freecodecamp: I get 500 errors on map and about after logging in

This usually happens when the servers cannot connect to your database. Can you verify that you have mongo up and running and that it reports new connections?

That's the first thing I checked:

Could the fact that it's a 32 bit VM have anything to do with it?

The last line there indicates that it waits for connections. But there is no indication that the server has connected. You should see something like this:

You might want to try and double check that the mongodb uri is correctly set in your environmental variables.

See: https://github.com/FreeCodeCamp/FreeCodeCamp/blob/staging/sample.env

Will do, thanks @BerkeleyTrue

Yes, that's set correctly in my .env file. Let me post some of my mongo log.

Can you post here exactly what you have for the mongo uri?

MONGOHQ_URL='mongodb://localhost:27017/freecodecamp'

Is mongo running within the same VM as the server?

It ran fine for one evening, so the info must be correct for it to make that initial connection and work. I'm thinking there is a lock on mongo from the previous session.

Yes, it's running in the same VM.

So there is definitely an issue making the connection:

MongoError: connection 0 to localhost:27017 timed out
at Function.MongoError.create (/home/vagrant/vagrant_node_modules/node_modules/mongodb-core/lib/error.js:29:11)

Which version of node/npm are you running in the VM?

no original function chain to wrap

This tells me there is an old version of some module running. You may want to wipe your node_modules and npm install again

Will try that now.

Put together this VM just for this site, so everything is most recent stable release:
vagrant@precise32:~$ node -v
v5.11.0
vagrant@precise32:~$ npm -v
3.8.7

And again, it ran fine the first day. So if anything was incompatible it wouldn't have ran at all right?

Reinstalling node modules now, so hopefully that resolves the issue.

Reinstalled node modules and am getting the same result. I will try tearing down mongo and all the data and reseed.

I reseeded and ran gulp again and the timeout error went away, however, the chain message did not:

I can still navigate around. It just seems to give the loopback timeout on the about page and map page:

I'm sure you are busy, so I'm going to try to figure this out on my own. Will update if I do so.

I just set up a new VM that is ubuntu 14 64 bit. Last one was Ubuntu 12 32 bit. I also changed the permissions of my mongo data folders to have same group and owner as my shared folder did (vagrant).

Everything is working now, so my guess is it was related to running mongodb in 32-bit mode.

Glad you sorted it out

Me too! Thanks for your help!

Everything is working now, so my guess is it was related to running mongodb in 32-bit mode.

Got the same error on a mongodb 32 bits machine. Migrating to x64.

I have a 64bit installation, but I get the same error. Rebuilding node_modules and seeding didn't help either.

Downgrade to 6.8.0

"git": "2.11", "node": "7.2", "npm": "3.10"

The node version is to be 6 (for instance I use 6.8.0, on macOS), can you try with the Latest LTS from https://nodejs.org.

Can someone post the actual error, not just the status code? Is it the same timeout error? A status code doesn't give us any information other than an error has occurred.

Of all the runs that I tested out this, I didn't see an actual Error in the logs. Here's the logs for gulp and mongod from the latest test runs. I did a mongod --repair before this step, and a search to determine (and kill) any running instances of node or mongod with - px ax | grep node and px ax | grep mongod, just to be sure.

And this is the "map" screen -

@Manish-Giri I think what Berkeley is looking for is the error that is returned if you browse to the path that returns the 500 error in the browser (/services/map;lang=en?_csrf=[TOKEN]&returnMeta=true) like in the first screenshot in this comment.
I can not reproduce this issue either.

@systimotic Okay, thanks for letting me know! I'll investigate and report.

I also have this issue. When I navigate to /services/map;lang=en?_csrf=[TOKEN]&returnMeta=true the browser returns:

{"output":{"message":"Cannot read property 'order' of undefined"},"meta":{}}

I fix this on my end by changing https://github.com/FreeCodeCamp/FreeCodeCamp/blob/staging/server/utils/map.js#L91 to

const result = map.result.reduce((result, supName) => {

This then results in a working map and the warning specified in #12006

{"output":{"message":"Cannot read property 'order' of undefined"},"meta":{}}

Sounds like the database isn't seeded correctly.

@systimotic I followed your instructions and visited that URL in the browser, this is what I get -

{"output":{"message":"Cannot convert undefined or null to object"},"meta":{}}

Update: I cloned the FCC repo to a different machine (Ubuntu 16.04, 64 bit), installed MongoDB, went through the all the necessary steps, upto npm run only-once and gulp. Yet, I came across the same Map error as in my other machine. Only the error message generated in the browser was different -

{"output":{"message":"Cannot read property 'order' of undefined"},"meta":{}}

which is the same as what @augmt reported earlier today. I'm not so sure now if this is a seed problem,
because I followed the steps to the dot, even on a new machine with a fresh mongo install.

Also, chaning line 91 in map.js didn't do anything in my case.

@BerkeleyTrue @Manish-Giri Alternatively I fixed my issue by just downgrading normalizr from 2.3.0 to 2.2.1.

If there's anything I can do to verify the integrity of the database, please let me know.

@augmt That could also be a possible cause

Since the bug has nothing to do with OP. closing in favor of #12103

Chaning line 91 in map.js fix my challenges...

What's the purpose of manifiest-rev.json?

@fizzvr please continue on #12103
