What happended?

I've tried to setup Medusa.js, PostgreSql, redis, through a docker compose file.
I got everything setup and running. And it served the http://localhost:9000/app route.

But then i get a white page. And an error about a missing index.ts

8:39:46 AM [vite] Internal server error: Failed to resolve import "/src/admin/i18n/index.ts" from "virtual:medusa/i18n". Does the file exist?

I've checked in the docker container. And the index.ts file exists.

/app # cat /app/src/admin/i18n/index.ts 
import en from "./json/en.json" with { type: "json" }

export default {
  en: {
    translation: en,
  },

So this seems to be a bug related to running Medusa.js in docker with pnpm?

My Docker file:

FROM node:20-alpine

# Install pnpm globally (small addition, ~10-20s extra on first build)
RUN npm install -g pnpm@latest

WORKDIR /app

# Copy lockfile + package.json first for caching
COPY package.json pnpm-lock.yaml* .npmrc*  ./

# Install dependencies with pnpm (uses your pnpm-lock.yaml if it exists)
RUN pnpm install --frozen-lockfile

COPY . .

# Make sure start.sh is executable in container too (optional but safe)
RUN chmod +x start.sh

EXPOSE 9000 7001

CMD ["sh", "./start.sh"]

My medusa-config.ts

import { loadEnv, defineConfig } from '@medusajs/framework/utils'

loadEnv(process.env.NODE_ENV || 'development', process.cwd())

module.exports = defineConfig({
  projectConfig: {
    databaseUrl: process.env.DATABASE_URL,
    http: {
      storeCors: process.env.STORE_CORS!,
      adminCors: process.env.ADMIN_CORS!,
      authCors: process.env.AUTH_CORS!,
      jwtSecret: process.env.JWT_SECRET || "supersecret",
      cookieSecret: process.env.COOKIE_SECRET || "supersecret",
    },
    databaseDriverOptions: {
      ssl: false,
      sslmode: "disable",
    },
  },

  admin: {
    // optional but recommended when running in Docker / separate origin
    backendUrl: process.env.MEDUSA_BACKEND_URL || "http://localhost:9000",
    vite: (config) => {
      return {
        ...config,
        server: {
          host: "0.0.0.0",
          allowedHosts: ["localhost", ".localhost", "127.0.0.1"],
          hmr: {
            port: 5173,
            clientPort: 5173,
          },
        },
      }
    },
  },

})

Expected behavior

Not a white page.
Not the import error in the backend.

Actual behavior

But then i get a white page. And an error about a missing index.ts

@RogierHelmerAtWork were you able to fix it? i followed the documentation here https://docs.medusajs.com/learn/installation/docker and it worked, but tried to get it ready for deployment and stopped working.

Also its a cool coincidence that you are building a perfume website. me too! I built one with WooCommerce but i found it too limiting.
