Should sideEffects be boolean false ? esbuild is complaining about it since the 128.0.0 release:

▲ [WARNING] The value for "sideEffects" must be a boolean or an array [package.json]

    ./node_modules/googleapis/package.json:9:17:
      9 │   "sideEffects": "false",
        ╵                  ^

1 warning

Webpack documents it similarly as boolean | string[]
