Problemas al desplegar la API a través de Heroku

Buenos dias @esegredo.

Estamos realizando el despliegue de la API tal y como aparece en los apuntes de clases, en los ultimos pasos ejecuto el push de heroku a main y luego visualizo los logs para ver si todo se ha desplegado correctamente, sin embergo en este paso se visualiza la siguiente informacion:

Por lo que entiendo que ha ido mal el despliegue y no entiendo a que puede ser debido puesto que en el package.json del proyecto tengo:


{
  "name": "ull-esit-inf-dsi-21-22-prct12-music-api-grupo-m",
  "version": "1.0.0",
  "description": "",
  "main": "dist/index.js",
  "scripts": {
    "coverage": "nyc npm test && nyc report --reporter=lcov",
    "doc": "typedoc",
    "test": "mocha",
    "heroku-postbuild": "tsc",
    "start": "node dist/index.js",
    "dev": "tsc-watch --onSuccess \"node dist/index.js\""
  },
  "engines": {
    "node": "18.x"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/ULL-ESIT-INF-DSI-2122/ull-esit-inf-dsi-21-22-prct12-music-api-grupo-m.git"
  },

y todas las dependencias instaladas. No se bien como solucionar esto, puesto que a mi punto de vista esta todo bien especificado.

Un saludo y gracias de antemano.
