Error when deploying Medusa backend on Railway

[jesusparfer27]

Hi everyone,

I'm trying to deploy my Medusa backend from the root directory on Railway, but I keep running into the following error during deployment:

[Region: europe-west4]

╭────────────────╮
│ Railpack 0.9.0 │
╰────────────────╯

↳ Detected Node
↳ Using yarnberry package manager

Packages
──────────
node  │  20.19.5  │  package.json > engines > node (>=20)
yarn  │  2.4.3    │  railpack default (2)

Steps
──────────
▸ install
$ yarn install --check-cache

▸ build
$ cd .medusa/server && npm run predeploy && npm run start

Deploy
──────────
$ yarn run start

Successfully prepared Railpack plan for build
...

The full log indicates issues with cache cleaning and some deprecated packages, and eventually the deployment fails.

Has anyone experienced a similar issue deploying Medusa on Railway using Node 20 and Yarn Berry? Could this be related to the .medusa/server structure or the way npm run predeploy is executed during build?

Any guidance on how to properly configure the backend for deployment on Railway would be greatly appreciated.``
