I had to comment out following line from /srv/nodebb/src/categories/recentreplies.js (line 188-196) to make my NodeBB run:

function getPostsRecursive(category, posts) {
//              category.posts.forEach(function (p) {
//                      posts.push(p);
//              });
//
//              category.children.forEach(function (child) {
//                      getPostsRecursive(child, posts);
//              });
        }

I'm not sure if this has anything to do with it, but when clicking on certain flags, following error happens. I think a user flagged his own message (somehow?!), however I'm not sure because I can't click on the flag without crashing NodeBB:

It seems as this is a database problem because I've retested this on a fresh NodeBB installation (while copying and reusing the database). I'm not that into Databases, so please let me know if I should post any command-outputs here for additional information.

For the first error see this, https://github.com/NodeBB/NodeBB/commit/157a7d1f0ed082f20345b9523ab4826dab1483d0

The second issue sounds like it is related to this https://github.com/NodeBB/NodeBB/issues/6925

uplift created this issue in NodeBB/NodeBB

closed Flag Detail Page causing server crash when reporter has blocked poster #6925

0 barisusakli committed to NodeBB/NodeBB

prevent possible crash if category.posts is undefined

[Tom_Rade]

@baris Thank you so much (especially for your fast response). That commit fixed everything!

Regarding the second issue, is there any possible fix? I'd really appreciate it.

[julian]

Yes, the second issue was fixed and is in latest master at the moment

[Tom_Rade]

@julian You're a real magician. This is crazy fast support. I'm absolutely stunned by NodeBB now. Not going to consider switching anymore because you fixed it. Thank you sooo much!

Could you post the commit-URL so I can edit it locally on my release-install?

[julian]

Yes, you can cherry-pick this sha to get it into your NodeBB

Edit: You just happened to catch me online at the same time, hah. The flag issue is also resolved from a couple days ago, so it wasn't done just now

[Tom_Rade]

@julian Alright, but if you made me aware of the commit/fix. And very fast.

I'll fix some horrible German translations (especially in the GDPR which is critical) as a favor. I hope Transifex gets merged soon (regarding: https://community.nodebb.org/topic/13269/missing-translation-string-user-watched_categories/).

You saved my 150k community from switching to phpBB

[PJ Legendre]

Hi, I'm getting a similar error message Cannot read property 'forEach' of undefined but in authentication.js:63:19. It started after I installed a couple of sso plugins: Facebook, Twitter, Discord, and Google. The cherry pick did not help me

[baris]

@PJ-Legendre please post the stack trace from logs/output.log

[PJ Legendre]

Thank you for getting back so quickly. Here it is:

I added a check so nodebb doesn't crash here You possibly activated an sso plugin that is not using filter:auth.init properly. Which sso plugins do you have?

[PJ Legendre]

Thanks so much for the fix! I activated these plugins:

• https://github.com/julianlam/nodebb-plugin-sso-facebook
• https://github.com/julianlam/nodebb-plugin-sso-google
• https://github.com/julianlam/nodebb-plugin-sso-twitter
• https://github.com/NathanSMB/nodebb-plugin-sso-discord

I assume the culprit might be the discord one?

[baris]

Yes, it needs to be updated so it doesnt pass back undefined to hook callback.

[PJ Legendre]

I will notify the plugin's creator, thank you.
