## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

```

this is the command that I issued to upgrade Discourse.

cd /var/discourse

Your Node version is incompatible with "/var/www/discourse".

Expected version: >= 20
Got: v18.20.4

This is happening because the package's manifest has an engines.node field specified.
To fix this issue, install the required Node version.
