Firebase Serve command failing with error 404

Question

Whenever I run firebase serve on my mac I am getting a 404 error...This has never happened before and I was just using the local dev server maybe 5 minutes before this started happening. I have deleted the firebase.json file and reinitialized it, reinstalled firebase tools but it fails every time. Here are the results from running the command in debug mode.

    firebase serve --debug

Answer 1

The issue is with Google. When you run firebase serve it makes a request to https://mobilesdk-pa.googleapis.com which is currently throwing a 404 error.

I was able to get around this (temporary fix) by editing 3 files in node_modules/firebase-tools/lib.

On line 99 of api.js is where the bad URL is being called. Simply change that to any valid non-404ing url.

Then, in fetchWebSetup.js, change the parameter on line 9 after "GET" to a blank string (e.g. return api.request("GET", "", {

Do that same as above to functionsConfig.js on line 51.

This should get you up and running for now, but this should resolve itsself when Google fixes that URL.
