B4J Question [ Jserver ] how to use JFirebaseServer in a websocket handler with Jserver?

[Waldemar Lima]

Hi everyone, I'm having trouble using JFirebaseServer with a websocket handler.
when connecting +2 users, from the 2nd an error occurs:

java.lang.IllegalStateException: FirebaseApp name [DEFAULT] already exists!

Websocket Handler ex:

Sub Device_VerifyToken(Params As Map)
    firebaseId = Params.Get("token")
    Log("tokeid = "&firebaseId)
    fs.VerifyToken(firebaseId)
End Sub

Sub fs_TokenVerified (TokenId As String, Success As Boolean, Token As FirebaseToken)
    If Success Then
        Log(Token.DisplayName)
        Log(Token.Email)
        Log(Token.Uid)
    Else
        Log("Error...")
    End If
End Sub

What to do in this case ?

1. Post the full stack trace.
2. You probably need to use a single instance. You can implement it in Main or in a single instance class.
