node ace build --production, [ error ] "build" command not found error on Digital Ocean Apps

Question

When trying to configure an application with the following deploy commands:

Build Command npm run build Run Command node build/server.js

The following error is thrown:

clinica-medica-backend@1.0.0 build
node ace build --production
[ error ]  "build" command not found
npm notice

npm notice Run `npm install -g npm@8.5.1` to update!
npm notice

For documentation on the buildpacks used to build your app, please see:

If you change the build command to: Build Command node ace

I don't know what exact version you are running on with adonis however the build command you are looking for is in the @adonisjs/assembler package which is installed as a dev dependency by default and I guess when you deploy you set the NODE_ENV environment variable to production by default which when the packages get installed on the server. only the normal dependencies get installed so either add the @adonisjs/assembler to the normal dependencies or you can make the NODE_ENV to be development which I do not recommend
