When using findOrFail() or findOneOrFail() from typeORM, a 500 error is returned if there is no entity (EntityNotFoundError).
To make it returns a 404, use an exception filter as described in https://docs.nestjs.com/exception-filters .

Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.
This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.
