  • Upgrade Jets: Are you using the latest version of Jets? This allows Jets to fix issues fast. There's a jets upgrade command that makes this a simple task. There's also an Upgrading Guide:
  • Reproducibility: Are you reporting a bug others will be able to reproduce and not asking a question. If you're unsure or want to ask a question, do so on
  • Code sample: Have you put together a code sample to reproduce the issue and make it available? Code samples help speed up fixes dramatically. If it's an easily reproducible issue, then code samples are not needed. If you're unsure, please include a code sample.

My Environment

Software Version
Operating System Amazon Linux
Jets 1.8.5
Ruby 2.5.1

Expected Behaviour

I would like to run jets server --port 8080 in Cloud9 to run a preview version of the site before deploy.

Current Behavior

The local server fails with a NoMethodError on lib/jets/controller/middleware/main.rb: in setup, line 35

Step-by-step reproduction instructions

  • Start a new Cloud9 host
  • Install and use Ruby 2.5
    • rvm install 2.5.1 && rvm use 2.5.1 --default
  • Install jets
    • gem install jets
  • Install yarn
    • npm install -g yarn
  • Install mysql client
    • sudo yum install mysql-devel
  • Start new project
    • jets new demo
  • Start the server on port 8080 as required by Cloud9
    • jets server --port 8080

Code Sample

NoMethodError at /
undefined method `request' for nil:NilClass
