This error happened while installing a direct dependency of /tmp/renovate/repos/github/3846masa/lit-date

Your Node version is incompatible with "[email protected]".

Got: v18.20.6

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