#

doesnt look like you are setting the correct cors headers, at least not on the root path

#

I have enabled all cors headers with app.use(cors())

#

where are you seeing this issue, your frontend https://worldengine.in seems to be able to call the backend https://worldengine-production.up.railway.app without issue

#

let me share a curl

#

However this is working locally

vale cave Sep 3, 2023, 8:22 AM

#

what am i supposed to do with that?

paper magnet Sep 3, 2023, 8:23 AM

#

Okay, thought it might help

vale cave Sep 3, 2023, 8:23 AM

#

if you are getting a cors error in the browser, you need to tell me me how to reproduce it in my browser

#

i got a 503 status code, this is your actual issue

#

first guess would be your app is crashing

#

is there anything in the deployment logs

#

okay looks like you have a code issue

paper magnet Sep 3, 2023, 8:27 AM

#

Okay deploying a quick fix

#

Can you pls try the visualise button again, Im now getting a 500

vale cave Sep 3, 2023, 8:32 AM

#

what version of node are you using locally and what version are you using on railway

paper magnet Sep 3, 2023, 8:49 AM

#

18.13.0 locally, how do I check on railway

vale cave Sep 3, 2023, 8:51 AM

#

it would be in the nixpacks build table in the build logs

paper magnet Sep 3, 2023, 8:53 AM

#

nodejs-16_x

vale cave Sep 3, 2023, 8:54 AM

#

alright then set engines.node to 18 in your package.json

paper magnet Sep 3, 2023, 9:01 AM

#

Sorry how do I do this

#

This is my package.json

vale cave Sep 3, 2023, 9:01 AM

#

set engines.node to 18

#

in your backend package.json

paper magnet Sep 3, 2023, 9:16 AM

always make sure the production environment is running as close to as what the development environment (your computer) is running
