Error on Heroku when trying to post data ( error:0909006C Pem routines..._

Question

I am trying to make a small nodeJS server deployed on Heroku, saving data to Firestore database. The server is deployed and running correctly. I use Insomnia to test my requests and when I use it locally I can send a post request and save my data object to the database without issues. However, when I try to send a post request to Heroku, I get a 500 error with this message:

{ "code": 16, "details": "Failed to retrieve auth metadata with error: error:0909006C:PEM routines:get_name:no start line", "metadata": {}, "note": "Exception occurred in retry method that was not classified as transient" }

I have read that it is necessary to add real line breaks in the env variable but I guess I am doing it already. This is my initializeApp function:

admin.initializeApp({
    credential: admin.credential.cert({
        projectId: process.env.PROJECT_ID,
        privateKey: process.env.PRIVATE_KEY
        ? process.env.PRIVATE_KEY.replace(/\\n/gm, "\n")
        : undefined,
        clientEmail: process.env.CLIENT_EMAIL
      }),
    databaseURL: "XXXXX"
  });

Any idea how to fix this?

As i see in this question: How to make an http DELETE request with JSON body in Flutter? the "delete" verb does not send data with Flutter. You can see @Roi Snir's answer in the previous link, a way to send data with "delete" by using the .Request method of the http package.
