Rails Heroku deploy: Precompiling assets failed. SassC::SyntaxError


I get an error "Precompiling assets failed" during deploy to heroku RoR project.

I tried to find css code with "calc(100vh - 110px)", but didn't find anything in the project.

What could be the issue? Thank you

Solution

  • fixed it by adding config.assets.css_compressor = nil to application.rb and production.rb + changed node.js version to "engines": { "node": "16.13.1" } In package.json
