Error deploying backend to railway

[livid radish]

Hello, so with 1.8.0 update I'm unable to deploy a newly created backend to Railway, I checked build logs and here what I found, any help would be appreciated

Replacing the build command in railway settings to babel src -d dist --extensions \".ts,.js\" fixed the issue

Replace yarn by npm, seems that yarn is not install in your deployment as it is written in the error message in your console

Hi there, I did what you said and it looks ok on the Railway dashboard but I cannot access the https.//mybackendurl/store/products. Every time I try, I got a 503 error on the browser console. Do you know why this happens? Thanks

Hello, idk really maybe try the solution adrien provided, the build command that I provided above was taken from medusa 1.7 but it works for me somehow 😅
