MQTT : rails mqtt:start problem

We are a group of student working on Farmbot.
We would like to have our own Farmbot web app based on our Server.
For this, we are using a Virtual Machine
We are having issues when typing the rails mqtt:start command :
It seems that the Erlang version used on our VM is not the same as the one used for the Farmbot.
Enclosed is our log file. log.txt (4.2 KB)

What version of Erlang is used for Farmbot.?

Thanks in advance


Thanks for bringing this to our attention and for providing the detailed error log. We use Docker to manage the Erlang version (source) which means it should use Erlang 19.3.1 every time without any need for configuration.

A few questions about your setup:

  • Is your server running any special code modifications other than the typical setup instructions?
  • What version of the app are you running? You can find out by running git log -1 --abbrev-commit from the Web App directory.
