@Nivix neither, as per the doc at https://docs.nodebb.org/en/latest/installing/cloud/heroku.html I have the following in my Procfile:

web: node loader.js --no-daemon --no-silent

Here is the log with --no-silent:

Any ideas / suggestions?

@julian Thanks, I understand that part better now. I added conditionals and now that error goes away. It seems to be working now as designed for that hook -- any suggestions regarding other hooks to use, to achieve the flow I described in my previous message in this thread?

Despite the error in the logs above, I just noticed that the plugin did do its thing, it logged in uid=1 regardless of what what user/pass was submitted.

So far, so good. but not quite the flow I was hoping for.

Here is what I am trying to achieve, maybe there is a better hook to use:

• user signs in our app, which is on a different subdomain from nodeBB (ie. app = app.domain.com and nodeBB = nodebb.domain.com)
• our app adds a session cookie for .domain.com (ensuring that other subdomains can access the cookie)
• user arrives at nodebb.domain.com
• plugin immediately gets triggered, and checks for the app session cookie
• if found, plugin does work to validate the session and identify the user
• if valid, login matching user or register new nodeBB user
• user logged in

All without the user needing to click the Login link, of course.

Any suggestions? The plugin, as it stands now seems to require a post of the local login form to get triggered, whereas ideally the following logic would happen: IF nodeBB session exists, use it ELSE: look for app session cookie as described above...

Okay, got past the first issue (after learning how to to do ./nodebb dev ) -- I needed to require winston in library.js.

Now I get an error when I try to submit the login form:

Thoughts?

I am in the earlier stages of writing my first plugin, a SSO plugin that is based off of the gist that @julian provided at https://community.nodebb.org/topic/812/using-php-sessions-with-nodebb/23:

My plugin is at:
https://github.com/contentblvd/nodebb-plugin-sso-session

And the library.js is almost identical to the gist above. The only change I made it to hardcode the uid variable, for early testing purposes. My thought was that it would auto login to the uid=1 user. (Later I plan to add the real logic for the login)

I have activated the plugin, but nothing happens, nothing shows in the logs either (./nodebb log). As suggested by @julian in the thread linked above, I am trying to use the action:auth.overrideLogin hook.

I am pretty sure I am missing something (or several things!). Any guidance is greatly appreciated.

I think I figured this out after trying to run it locally,

The Heroku install steps say to add the follow dependencies to you package.json:

 "dependencies": {
     ...
     "nodebb-plugin-dbsearch": "0.0.10",
     "redis": "~0.10.1",
     "connect-redis": "~2.0.0"
 },
 "devDependencies": {

But looking closer, nodebb-plugin-dbsearch is already in the package.json at a higher version. This conflict seemed to cause the crash.

I am guessing that recent versions of nodeBB have changed so this part of the doc is no longer applicable. Here is a pull request to adjust the docs, if I am correct in this assumption:

https://github.com/NodeBB/nodebb-english/pull/51

I am new new to nodeBB, excited to get things going!

I followed the instructions at:
https://docs.nodebb.org/en/latest/installing/cloud/heroku.html
to install on Heroku and all of the steps seem to go smoothly,

But when I try to view the app, I get a (standard Heroku) "Application Error" message.

Looking at the logs I found the follow, which doesn't seem to provide much insight:

Thoughts? Are there ways to enable a debug mode to help troubleshoot the reason for the crash?

I am interested in SSO as well. I have seen several threads that mention the "how to" as described by @julian above, but haven't yet seem any real world examples or replies from folks who have done it. I would be great to hear some such examples.

(We are trying to make a decision between nodeBB and Discourse. I like what I am learning about nodeBB so far, but SSO may be important for us. Looking for some added confidence that we'd be able to get an Oauth2 endpoint setup on our app, which is powered by node)
