error passing empty credentials to firestore emulator

I am trying to seed some sample data into my local firestore emulator database. I adapted the example from this github issue

My code looks like this:

const {Firestore} = require('@google-cloud/firestore');
const {credentials} = require('grpc');

const db = new Firestore({
  projectId: 'my-project-id',
  servicePath: 'localhost',
  port: 8100,
  sslCreds: credentials.createInsecure(),
  customHeaders: {
    "Authorization": "Bearer owner"
  }
});

async function load_data() {
  await db.collection("mycollection").doc("myid").set({ foo: "test" })
}
load_data();

But I receive the error

this.credentials._getCallCredentials is not a function

Tested on node 10 and 12 with same error.

Library versions:

Is there a better approach to writing to local emulated firestore? Or is there something wrong with my code?

The problem here is that you're trying to use two different implementations of gRPC together. Internally firestore uses @grpc/grpc-js, so that is what you should be using. You should only need to change the second line to const {credentials} = require('@grpc/grpc-js'); and switch the dependency to that library.
