Seeing error "Error: Client is Offline" in firebase functions?

[Phil Hodey]

Hi,

I have recently noticed lots of failing firebase functions when reading or writing to the realtime database. I've raised this with support but in the meantime, has anybody else seen this message?

I've never seen it before and as it seems to be widespread across all functions I am not sure where to start looking to debug the issue. I am using 9.5.0 firebase-admin.

I've investigated further and the errors go back to the 20th February, this is the date I updated all realtime database functions to use the .get() syntax released in 9.5.0. 

I've reverted to 9.4.0 and .once('value') syntax and I have not yet seen a recurrence of the issue. Anybody else seen a similar issue?

I experienced the same issue in version 9.6.0. Using the .get() method failed intermittently for unknown reasons. I reverted back to 9.4.0 and used the .once method, and that seemed to fix the issue.

I have the same issue as well.  Also for calling `get` from firestore. reverting from 9.5.0 to 9.4.0 seemed to do the trick

Hello!  

Thanks for the reports. We were wondering if you were able to collect any logs for these errors? This would help us determine whether this is a known issue that we are working on (a missing index lookup) or something new.

Thanks

I found a temporary fix by declaring db = admin.database().ref() instead of db=admin.database() on initialization, then calling db.child() instead of db.ref() in the deployed functions.

Getting the same error here about 80% of the time.

index.js:

---

const app = admin.initializeApp({

     ...functions.config().firebase,

        databaseURL: 'https://ahs-app.firebaseio.com'

}, 'main' )

const db = admin.database(app)

exports.publishStory = functions.database.instance('ahs-app').ref('/storys/{storyID}').onWrite( async changes => {

     // ...

     const schemas = await db.ref('schemas').get().then(x=>x.value()) 

     // ...

})
