Heroku install went smooth, but app crashes immediately



  • 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?

    What do you see in the nodebb log? It should be in logs/output.log



  • 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    I am guessing that recent versions of nodeBB have changed so this part of the doc is no longer applicable.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:
