Hey there! We've found the following might help you get unblocked faster:

• 🧵 NestJS deployment
• 🧵 My deploy is failing, keep referring to jwt_secret
• 🧵 Nestjs p-throttle deployment

If you find the answer from one of these, please let us know by solving the thread!

how do you deploy? it seems like you didn't build the app

im deploying via github and i have the following command in my Procfile web: npm run build && npm run start:prod

can you try copying npm run start:prod in Setting => Deploy => Custom start command?

still didnt work here is my github repo https://github.com/justmexmehak/emr-backend

can you check the root directory in Settings => Source => Root Directory? if you see /app replace it with /.

Also I can see that start:prod has also npm run build so what I would suggest is for now to create a new script:

"start:railway":"node dist/main.js"

and try with this script.

If it doesn't work then I can't help you and you will need to wait for someone else 🙂

Have you tried to build the project locally ? Running the production build locally triggers the same error?

it seems after deploying for production /dist.main.js file doesn't exists

Modify your nest-cli.json (Add output path)

{

"$schema": "https://json.schemastore.org/nest-cli",

"collection": "@nestjs/schematics",

"sourceRoot": "src",

"compilerOptions": {

"deleteOutDir": true,

"outputPath": "./dist"

}

}

then place npm run start:prod in Setting => Deploy => Custom start command on Railway Service setting
