Deploying Rails, but getting Node error?

1

Hey everyone, I was updating an older Rails application (Rails 6.0.0, Ruby 3.0.1) I was running without problems. Just changed a few lines of text in the HTML, so theoretically no big cause for concern.

But when I pushed to Github, I got an error that seems somewhat “disguised”, early on it’s complaining about a node version, and later getting a build error caused by sprockets-3.7.2. I’m not using Node explicitly that I know of, so is there some dependency issue I need to attend? Maybe I’m missing something about the default platform versions? A bit lost, if anyone can help, would appreciate.

Here’s the Gemfile and the logs.

Add node --version to the start of your render-build.sh script;

In an effort to reduce image sizes, Node is available as a stub on non-Node services, the first time it is invoked it is loaded in. However, this includes the output we add about the version of it (and Bun) being used. You can see in the “JSON::ParserError” bit that there is version information with a trailing ["ok"]. ["ok"] is supposed to be the only thing printed, but the rest of our output causes the entire chunk of output to be invalid JSON.

Thus, you need to fully load Node in before it is needed to be used (by execjs I assume?).

Thanks, Jason.

I did as you said and added node --version to the start of my render-build.sh script. It worked, it built and deployed. I don’t know if it’s being used by execjs, like you mentioned.

Just so I understand this for the future, it has nothing to do with the Ruby or Rails version itself, it’s just for image compatibility across your platform. Does this apply to all projects, or Rails projects?

Thanks for your help.

This applies to all non-Node services. Node is available in every Native Environment type (Ruby, Python, Go, not Docker though) because of its prevalence in frontend design, but it is only a stub on non-Node services. Obviously on Node services it is immediately available.

Understood, makes sense. Thanks for clearing it up.

All the best.
