In local Firebase, how do I set a projectId for the current environment?

Question

I'm trying to write some test data to a local version of Firebase. I have these variables defined in my .env.local (and .env.development files) ...

REACT_APP_MB_ACCESS_TOKEN="accesstoken"
ALGOLIA_APP_ID="appid"
ALGOLIA_API_KEY="apikey"
NODE_ENV="development"
FIREBASE_EMULATOR_HOST_VAR=localhost:9000
FIRESTORE_EMULATOR_HOST=localhost:8080
GCLOUD_PROJECT=mutualaid-123f6

I have the below set up (via npm run dev:upload) to upload dummy data into my local Firebase ...

const admin = require("firebase-admin");

const data = require("./data.json");
let serviceAccount = process.env.FIREBASE_SECRET;
...

  require("dotenv").config();
  admin.initializeApp();
  db = admin.firestore();
...

async function upload(data, path) {
  console.log("starting ...");
  return await db
    .doc(path.join("/"))
    .set(data)
    .then(() => console.log(`Document ${path.join("/")} uploaded.`))
    .catch((e) => {
      console.error(`Could not write document ${path.join("/")}.`);
      console.log(e);
    });

adly the above results in

...
Could not write document organizations/1/missions/aaf3c03c33ecf79e3d7ffddf401c01f0.
Error: Unable to detect a Project Id in the current environment.

or all data in my data.json file (examples of it are below). What else do I need to configure to get this data into my local Firebase?

{
  "organizations": {
    "1": {
      "missions": {
        "aaf3c03c33ecf79e3d7ffddf401c01f0": {
          "status": "started",
          "missionDetails": {
            "dummy": "This is only here because upload modules did not understand that we want this to be a field",
            "needs": [
              {
                "name": "Fruits & Veggies Medley",
                "quantity": 1
              }
            ]
          },
          "uid": "aaf3c03c33ecf79e3d7ffddf401c01f0",
          "deliveryConfirmationImage": "",
          "feedbackNotes": "",
          "groupUid": "Daly City 2020/03/05",
          "organizationUid": "1",
          "volunteerDisplayName": "Michael Williams",

            "timeWindowType": "as soon as possible",

          },

You haven't passed your config object to admin.initializeApp

Since you use dotenv to load env files, you can create a config object with env details like

const config = {
    type: "service_account",
    project_id: "xxx",
    credential: 'your credentials'
};

require("dotenv").config();
  admin.initializeApp({config});
  db = admin.firestore();

If you are not passing any config to initializeApp then you need to define it FIREBASE_CONFIG env object.

According to the documentation:

The SDK can also be initialized with no parameters. In this case, the SDK uses Google Application Default Credentials and reads options from the FIREBASE_CONFIG environment variable. If the content of the FIREBASE_CONFIG variable begins with a { it will be parsed as a JSON object. Otherwise the SDK assumes that the string is the name of a JSON file containing the options.
