MongoError: Mod on _id not allowed

[Surfoo]

Hello,

I tried to install Rocket.Chat (from master) on my own server (Debian Wheezy with Apache, no nginx, no ssl), and on the startup, I have a 503 error.

In the err-0.log I have:

What can I do to fix the issue?

[geekgonecrazy]

What version of mongo are you running? Meteor requires 2.6 or greater. We've been trying to stay compatible with the 2.4 but its on ongoing battle.

[Surfoo]

With wheezy-backports, it's 2.4.8

[geekgonecrazy]

Give 2.6 or 3.0 a shot. Check mongodb's website. I think the have Debian repos for more up to date versions

[Surfoo]

Thanks it works with the 3.0.6 version! I registered the first account, but I can't find the Administration.. Where it is?

[geekgonecrazy]

@Surfoo did you create the user before upgrading? Its possible it didn't successfully make it admin.

[Surfoo]

Hum, no after the upgrade, because with mongo 2.4 I had a 503 error. How can I fix that?

[rwakida]

Hi @Surfoo there was a bug with assigning 'admin' role to the first created user. I submitted a fix, but until that gets merged to master, you can simply restart meteor. At startup, RocketChat will assign the oldest user the 'admin' role IF no admin already exists.

[Surfoo]

OK, thanks. How can I restart meteor?

[rwakida]

Or you can manually update the user in mongo. The user should have the following role:

"roles" : {
        "__global_roles__" : [
            "admin"
        ]
    },

[Surfoo]

I'm totally newbie with mongodb, I think restart meteor is easier than update the db :)

[geekgonecrazy]

@Surfoo how did you start meteor? If you just cloned and then typed meteor. Then a ctrl+c will work. If you used pm2 you will have to do a pm2 restart like you did during setup.

[rwakida]

@Surfoo, I've been using mongodb for a while and I still feel like a newb. 😄 .

If @geekgonecrazy's advice doesn't work for you, join the rocket chat demo and talk to the devs for realtime feedback.

[Surfoo]

ok, I restarted the app with pm2, it works, and I have my admin account :-)

Upgrading to newset MongoDB Version fixed the isee

[geekgonecrazy]

👍

[mikevanwinkle]

👍 updating mongodb worked for me

[r00t4bl3]

👍 I use mongodb version 2.4 and after node main.js it shows this error. After upgrading to 2.6 and it runs perfectly. I think the manual should be updated so it says minimal mongodb version is 2.6.
