Deployment problem : assets are not served (404) (build/client/assets)

[GuyoST]

Hello every one,

I was very happy to complete the migration from remix to react-router 7 (framework), and I encounter a problem when deploying on the server :

• NodeJS 22
• Ubuntu 22.04

I deployed this files :

• package.json
• package-lock.json
• build (folder)

then i ran npm i and npm start

but I get these logs in the console (for all assets) :
GET http://www.taximoov.com:3006/assets/entry.client-Cyskf7M-.js --> 404 (or 500 because i have a splat route (*) that matches anything otherwise).

I deployed on 2 servers, same OS and versions of nodejs :

• first server : I got the problem, but I could make it work finally by uploading the full "dev" app (source code) on the server, and then compile it on the server, and then run npm start, and it was working... but I guess it's not the best way to do.

• second server : same problem : but unfortunately, I tried to compile it, but i get : "sh 1 : react-router not found", even if node modules are installed correctly.

I can see the GET request in the terminal, for example :
GET /assets/global-utils-wrG9T8G9.js

I tried to run the server in production on my development computer, and it's working fine, assets are served correctly.

Does anyone has an idea about what I forgot to do to make it work ?
I tried with react-router 7.2.0 (first server), and 7.3.0 (second server), same problem.

I hope someone can help me to fix this, or help me understanding what's wrong... because i'm lost. I don't know what else I could check.

THank you 🙂

I don't know if that can be useful : i'm using nvm to switch to node 22 to start the react-router server :

nvm use 22
npm start
