Getting error on deploying nestjs app on google app engine. The deployment worked fine but app is giving error
Here is the my package.json file
"main": "dist/main.js",
"engines": {
"node": ">=8.0.0"
},
"scripts": {
"prebuild": "rimraf dist",
"format": "prettier --write \"src/**/*.ts\" \"test/**/*.ts\"",
"start": "node ./dist/main.js",
"start:dev": "nest start --watch",
"start:debug": "nest start --debug --watch",
"start:prod": "node dist/main",
"lint": "tslint -p tsconfig.json -c tslint.json",
"test": "jest",
"test:watch": "jest --watch",
"test:cov": "jest --coverage",
"test:debug": "node --inspect-brk -r tsconfig-paths/register -r ts-node/register node_modules/.bin/jest --runInBand",
"test:e2e": "jest --config ./test/jest-e2e.json",
"build": " tsc -p tsconfig.build.json",
"gcp-build": "npm run build"
},
and this my app.yaml file
runtime: nodejs10
env: standard
I tried to see the error on gcloud console by gcloud app logs read and it gives me error in cjs/loader file
The app is working fine locally. Any reason why this is happening?

Error: Cannot find module 'src/utils'
It looks like you are using non-relative imports and using src as a root, which won't work once you have transpiled from typescript to javaScript without some extra modifications. The src directory shouldn't exist when you are in your production environment, only the dist that has your JavaScript. If you change the import to be a relative one (using .. to get tot the correct directory from where you are) it should work just fine
