Haven't a specific version of node here: https://github.com/fiqus/coophub/blob/master/.github/workflows/test.yml#L14

Maybe will be good use this action: https://github.com/skjnldsv/read-package-engines-version-actions and change the package.json to specify the engines that this project is able to use.
