strapi-tool-dockerize: npm run build fails

Hello

I was just trying your dockerize tool but I run into a problem. Everything goes fine, creates .env, Dockerfile, compose file etc… but when I actually run docker-compose up -d I get below error

failed to solve: executor failed running [/bin/sh -c npm run build]: exit code: 1

Any idea why this is failing?

When I do everything manually, it works fine. npm run build is there.

Update: this is the debug log output
