How to check logs of nexjs project deployed in google app engine standard environment?

Question

I have created nextjs project with Isomorphic admin theme

Now I am going to deploy this project to google app engine. I read this discussion and structured my app based on this repo

This is my app.yaml

env: standard
runtime: nodejs14
service: default

handlers:
  - url: /.*
    secure: always
    script: auto

and my package.json file

... ...
"scripts": {
    "dev": "next -p 3030",
    "start": "next start",
    "serve": "next start",
    "build": "rimraf build && next build",
    "deploy": "gcloud app deploy --project [Project-ID]",
    "analyze": "cross-env ANALYZE=1 next build",
    "heroku-postbuild": "npm run build"
  }
... ...

I added build dir and deployed to google app engine,but it shows 500 error.

1. Where can i check server error log? I guess that nodejs server didn't start correctly, but no way to check error message.
2. Should I use cloud-build and build-triggers to automate deployment on github commit? What is the best approach to deploy nextjs project to app engine?

To view your logs in Production,

1. Login to Google Cloud Console i.e. https://console.cloud.google.com
2. Click the hamburger menu icon (the 3 short horizontal rows) and in the drop down, look for Operations and under it Logging
3. Select legacy log viewer
