Pushing to Heroku

[rob]

Hey there,

I'm trying to deploy an instance to Heroku. Download the latest git, ran the build script which takes the basic details on Mongo URL etc through the CLI... I can run with ./nodebb start - I've added the Procfile like in the documentation, added build, process.json etc to the git and committed... but when I push to Heroku I get this:

NodeBB rob$ git push -u heroku master

Any ideas?

@rob any way you can use a heroku instance with an older version of Node / npm?

Hey Pita

Wanted to post earlier but had to wait for the post to be accepted, but you are correct. In case anyone else has the issue, this was it:

In package.json the 'engine' line for node was =>10 so Heroku was choosing Node 15. Manually changed that value to the same as what works for me locally 12.14.1 - all works well. Now having fun setting up nodebb-plugin-session-sharing - cheers!!
