gRPC：14 UNAVAILABLE：すべてのアドレスへの接続に失敗しました

grpcがタイムアウトする前に、jest test()非同期関数を100000msキャップに設定しても、接続に失敗します。

なぜこれが起こっているのか誰かが知ることができますか？ドキュメントを見ると、これは下位レベルのライブラリのようです： https://grpc.github.io/grpc/node/

更新

サーバー/エミュレーターがgRPCで見つからないことが示唆された後、私はfirebase serve --only functions,firestore。ターミナルでは、両方のサービスの異なるポートで実行されているエミュレータが表示されました。再実行jest --watchは少し異なるエラーを生成します。

Firebase関数は根本的なエラーを隠していました。これは2つのステップで解決されました。

  1. firestore.setLogFunction（）で管理SDKのロギングを有効にする
  2. projectId testProjectは無効でした。 projectIdをすべて小文字のtestprojectに変更すると、このエラーはクリアされました。
