firebase deploy --debugで詳細を見てみる

対応

functions.yamlがないとのことだが、諸々調べてみたところ以下の様に、手動でファイルをコピーすれば良さそうとのこと

コメントを参考に以下を実行してから firebase deployで問題なくデプロイできた

$ mkdir .output/server/node_modules/.bin
$ cp -r node_modules/.bin/firebase-functions .output/server/node_modules/.bin
$ rm -rf .output/server/node_modules/firebase-functions/node_modules/protobufjs
$ cp -rfu node_modules/firebase-functions/ .output/server/node_modules
