Express.js app doesn't work

[andsiand]

Hello, i made an express.js app, basically a webhook that when receives a post request, it sends an email when some conditions are met.

Everything works well locally, tested with ngrok and postman.

When i upload it on Filezilla server of my website, in a folder specifically made for this objective "mywebsite/webhook/" test, i get
403 - forbidden if i make a post request on folder url
405 - method not allowed if i make a post request on the server.js file inside the folder

I am not a developer and not expert in filezilla. What am i missing to make the webhook work as it did locally?

Also: searching online, looks like i shouldn't upload the node modules folder since i have the package-json file. Do i need to do some npm install somewhere, or it is automatic?
Thanks

This has nothing to do with FileZilla.

Uhm, i thought since locally it works, and on filezilla it doesn't, there might be some permission/authorization issue or something i am missing to make it work live.
Well, if anyone has some advice that can point me in the right direction, i'll be grateful.
Thanks anyways!

A start would be to check your webserver configuration.

Thanks, you're pointing to the fact that my web server might not be able to run node js applications right?

Exactly.
