First, we were trying to test this integration out locally with the Supabase local containers (`supabase start -x vector`) running on a dev machine alongside the Firebase emulator (`firebase emulators:start --import=firebase_local`). Our client is a Flutter app that uses the supabase_flutter and firebase_auth libraries. When the Firebase user is signed in on our app and makes a request to our Edge Function endpoints running locally, we see this error output from the `supabase functions serve` logs: ``` TypeError: Key for the none algorithm must be of type CryptoKey.
