I have a cloud function that does nothing with access tokens or authentication. I don't believe I've changed the cloud function in any meaningful way, it was working 30 minutes ago. Now it produces an exception.

Error getting document: { Error: 16 UNAUTHENTICATED: Getting metadata from plugin failed with error: Could not refresh access token.
    at createStatusError (/user_code/node_modules/firebase-admin/node_modules/grpc/src/client.js:65:15)
    at ClientReadableStream._emitStatusIfDone (/user_code/node_modules/firebase-admin/node_modules/grpc/src/client.js:271:19)
    at ClientReadableStream._receiveStatus (/user_code/node_modules/firebase-admin/node_modules/grpc/src/client.js:249:8)
    at /user_code/node_modules/firebase-admin/node_modules/grpc/src/client.js:715:12
  code: 16,
  metadata: Metadata { _internal_repr: {} },
  details: 'Getting metadata from plugin failed with error: Could not refresh access token.' }

The full function (forgive my bad Node) is below.

I haven't changed any security settings either, between the time it worked and stopped working.

Any thoughts?

'use strict';

const functions = require('firebase-functions');

exports.decrementLikeCountOnSighting = 
 functions.firestore.document('users/{userid}/sightings/{sightingid}/likes/{likeID}').onDelete(event => {
    console.log("decrementLikeCountOnSighting")
    var deletedValue = event.data.previous.data;

    const sightingRef = event.data.ref.parent.parent 

    return sightingRef.get().then((doc) => {
        console.log("In sub thingie")
            if (doc.exists) {
                var sighting = doc.data();
                var newNumberOf = sighting.numberOfLikes - 1
                console.log("Number of likes = ", sighting.numberOfLikes)
                return sightingRef.set({
                    numberOfLikes: newNumberOf
                }, {merge:true})
            } else {
                // doc.data() will be undefined in this case
                console.log("No such document!");
            }
            return true
        }).catch((error) => {
            console.log("Error getting document:", error);
            return false
        });
    })

We've been experiencing the same thing. A redeploy go the function seemed to fix it. Potentially linked to: https://status.firebase.google.com/incident/Functions/18011

More widely we've been having problems with anything loading. There must be another issue that they haven't reported yet.

Hello,

thanks for reporting this issue. We deployed a new version of google-gax that addresses this issue (0.14.5 as per https://www.npmjs.com/package/google-gax). If you redeploy your function, GCF will automatically pull in this patch release.

Please let us know if this issue is not resolved.

Sorry for the inconvenience,

Sebastian
