TypeError: Cannot read properties of undefined (reading 'split')

inna

Around a month ago I did upgrade NodeBB (not sure from which version, to 2.4 or 2.2) and also Node (from 16 I think to v18.7.0), and after that I'm getting this error:

TypeError: Cannot read properties of undefined (reading 'split')

This is what I see in web browser.
This is what I get in nginx's error log:

2022/08/14 15:57:08 [error] 674481#674481: *77854 upstream prematurely closed connection while reading response header from upstream, client: MY_IP, server: pythonforum.ir, request: "GET /post/1881 HTTP/1.1", upstream: "http://127.0.0.1:8080/post/1881", host: "pythonforum.ir"

I'm running nodebb as a systemd service and it is up.
This is /home/path/to/nodebb log:

Do you help me what is wrong with it? I tried many thing, like using old backup for both database and files but it did not help me.

Seems like nodebb can't find the meta.config object on your instance on this line https://github.com/NodeBB/NodeBB/blob/master/src/middleware/helpers.js#L60

Can you check the database nodebb is connecting and look for the config object? In mongodb the command would be db.objects.findOne({_key: "config"});

inna

@baris this is my helpers.js:

parts.push(`theme-${meta.config['theme:id'].split('-')[2]}`);

This is git status:

root@server:/home/nodebb/src/middleware# git status
On branch v2.x
Your branch is up to date with 'origin/v2.x'.

nothing to commit, working tree clean

There's nothing difference between my files are git.

Database connection works fine, I checked it and tried with both Mongo Compass, and mongo command with username and password authentication.

inna

Any updates?

@inna please execute the mongo command baris provided, and post the result

inna

Hi, this is the result, it's null:

root@iran:/home/nodebb# mongo
MongoDB shell version v4.0.28
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("SOMEID") }
MongoDB server version: 4.0.28

> db.objects.findOne({_key: "config"});
null

@inna you'll need to select the NodeBB database then run the command.

inna

Hi, that's it:

> use nodebb
switched to db nodebb
> db.objects.findOne({_key: "config"});
null

inna

@inna said in TypeError: Cannot read properties of undefined (reading 'split'):

Hi, that's it:

> use nodebb
switched to db nodebb
> db.objects.findOne({_key: "config"});
null

That's when authorization is disabled and I get the above output.

The following is when authorization is enabled:

> db.objects.findOne({_key: "config"});
