Android Question firestore - catching PERMISSION_DENIED exception

Andrew (Digitwell) · May 8, 2019

@DonManfred ,
I have am trying to access a collection which requires specific authentication.

Sometimes the authenticated user is not authorised to access the collection.

the Fetch call raises an exception, with PERMISSION_DENIED which is fine.

However, I cannot catch it in the B4A code. Is it possible to pass this exception up to B4A please.

Thanks

B4X:

Try
  collref.limit(100).fetch("allgames")
  wait for allgames_snapshot(gamessnap As QuerySnapshot)
    Catch
        Log("Cannot fetch " & LastException.Message)
        Return
      End Try
' ....other stuff

Did you see a "onFailure" in the log?

DonManfred · May 8, 2019

Try V0.59 (Dropboxlink from puchase) - untested

Note that the signature of the Event Snapshot has changed.

B4X:

Snapshot(success As Boolean, snap As QuerySnapshot, Info As String)

@DonManfred ,

no need to mention my name. If there is a Thread with Firestore in the Title i´ll see it most probably

Andrew (Digitwell) · May 8, 2019

Thanks. Could you send me the Dropbox link again. I don't seem to have it anymore.

DonManfred · May 8, 2019

See PN. Please bookmark the link for the future.

Andrew (Digitwell) · May 13, 2019

Sorry for the delay in replying.

The new version 0.59 is still not right. Here is the code I am using

B4X:

    Private collref As CollectionReference = fs.collection($"gametype/${gametype}/games"$,"games")
    Private gamessnap As QuerySnapshot
    If (collref <> Null) Then
        Try
            Log("Before fetch")
            collref.limit(100).fetch("allgames")
            Log("Fetching")
            wait for allgames_snapshot(gameret As Object)
            Log("after snap")
            If (gameret Is QuerySnapshot) Then
                gamessnap = gameret
            Else
                Log("Query failed" & gamessnap)
                Return gamelist
            End If
            
        Catch
            Log("Cannot fetch " & LastException.Message)
            Return gamelist
        End Try

If I let the code just run I get:

However, If I step through the code with the debugger then the code works.
