When I try to start the shell for local testing from the functions directory in my project, the emulator starts but my functions are not able to be loaded.
When I run "npm run build" I receive no errors. What is happening?
I have tried removing the functions directory and creating it again using the firebase-tools cli but I still get the same error. I have also exported the admin credentials.
I'm using the default method created in the index.ts file generated from the firebase-tools cli.
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp();
// // Start writing Firebase Functions
// // https://firebase.google.com/docs/functions/typescript
//
export const helloWorld = functions.https.onRequest((request,
response) => {
response.send("Hello from Firebase!");
});
I expect the emulator to spin up instances of the function for testing but instead, I see this error:
✔ functions: Emulator started at http://localhost:5001

⚠ We were unable to load your functions code. (see above)
- It appears your code is written in Typescript, which must be compiled before emulation.
- You may be able to run "npm run build" in your functions directory to resolve this.
If you are experiencing this error, run npm install firebase-functions@3.0.2 in your functions directory.
This will be fixed soon, and you can follow along here: https://github.com/firebase/firebase-tools/issues/1480
I found error in:
node_modules/firebase-tools/lib/emulator/functionsEmulatorRuntime.js
line 276:
const _onRequestWithOpts = httpsProvider._onRequestWithOpts;
should be:
const _onRequestWithOpts = httpsProvider._onRequestWithOptions;
Downgrade firebasefunction to version 3.0.0
Delete node_modules then run npm install, npm install firebase-admin and npm install firebase-functions@3.0.2
