App crashing right away after deploy from Github Actions - node.js

Question

Well, I have pushed my TypeScript project to github, and it has these scripts:
"scripts": {
"test": "jest",
"test:cov": "jest --coverage -i",
"test:unit": "jest unit --coverage -i",
"test:int": "jest int --coverage -i",
"build": "rimraf ./dist && tsc",
"start": "node ./dist/index.js",
"dev": "ts-node-dev --respawn --transpile-only --inspect -- ./src/index.ts"
}
After that, I created a github action workflow, making it run my tests and if they all pass, it deploys to heroku, but when the deployment is made, the heroku app crashes instantly.
This is the workflow:
main.yml:
name: Main workflow

This is the last action that I triggered: https://github.com/joaocasarin/test-selfapi/actions/runs/1365239970
This is the repo: https://github.com/joaocasarin/test-selfapi/
This is the log after the deployment to heroku:

Can someone please give me a light? This is the first time I try github actions.
Thanks

As Bertrand said, there was something wrong with the mongodb connection, so I just found that the variable MONGODB_URL was not set, only the test one was, so it was making the app crash because it was undefined for mongoose, making it exit.
