If you want to chain commands, run bash:
release_command = "bash -c 'npx prisma migrate dev && node dist/seeds/seeds.js'"
As an alternative, add a “release” script in your “package.json” and run it:
release_command = "yarn run release"
If you shell in, you can find node at /root/.volta/bin. Try running:
export PATH=/root/.volta/bin:$PATH
