I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @Capricair, thanks for reaching out to us. If you are receiving this error, it means that this method should be use in the regular client code and not in service worker. Cookies aren't available in service workers, and Analytics requires cookies to work.

This seems to be out of scope for Firebase JS SDK. There doesn't seem to be a bug, and Analytics will not work in a service worker context and for additional information (see #2243 (comment)). I'll be closing this issue now. If you encounter another issue, feel free to create a new one.
