This error happened while installing the dependencies of @google-cloud/[email protected]

Your Node version is incompatible with "registry.npmjs.org/cloudevents/8.0.2".

Expected version: >=16 <=22
Got: v24.11.1

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