@mannes-paqt Downgrading the "reflect-metadata" version in your package.json file might resolve this issue.

   "reflect-metadata": "^0.1.13",

I am also facing the same issue and it needs to be fixed by the maintainers for this repository as they have fixed the peerDependcies like below. [Refer]

  "peerDependencies": {
    "@nestjs/common": "^8.0.0 || ^9.0.0 || ^10.0.0",
    "@nestjs/core": "^8.0.0 || ^9.0.0 || ^10.0.0",
    "reflect-metadata": "^0.1.13",
    "rxjs": "^7.2.0",
    "sequelize": "^6.3.5",
    "sequelize-typescript": "^2.0.0"
  },
