heroku Verifying deploy... done. の後、表示されないエラー

Question

heroku へdeployした後、アクセスしても表示さず、logをみると、
bundler: failed to load command: puma (/app/vendor/bundle/ruby/2.6.0/bin/puma)

2020-02-06T04:30:08.289271+00:00 app[web.1]: Errno::ENOENT: No such file or directory @ rb_sysopen - tmp/pids/server.pid
この辺りが原因？で見られないのかと思い、
調べてtmp/tmpの下に、pidsとsocketssocketsのフォルダを作ってみたのですが変わらずで、行き詰っています。
どなたかお知恵を貸してください。
