Android Question Exception No data with HttpJob

[ziz]

Hello you all

When requesting to read data from FireBase that does not exist, the application closes and collapses with this line

 Dim root As Map = parser.NextObject

Of course, this is normal
Is there a way to avoid this problem ?

Public Sub ReadData(LinkSuffix As String, Token As String,RequestTag As String)
    Dim hj As HttpJob
   
   
    hj.Initialize("readdata",Me)
    hj.Tag = RequestTag
    Dim RequestURL As String = BaseURL & LinkSuffix & ".json"
    If Not(Token = "") Then
        RequestURL = RequestURL & "?auth=" & Token
    End If
   
    hj.Download(RequestURL)
  
    Wait For (hj) JobDone(hj As HttpJob)
    
    If hj.Success Then
         
        
        Dim parser As JSONParser
        parser.Initialize(hj.GetString) 
         
        
        Dim root As Map = parser.NextObject
   
   
End Sub

1. Always post the error message from the logs.
2. What is the output of: Log(ht.GetString)?

 

[KMatle]

Yes. Check, the result of ht.getstring:

Starting with "{" -> it's a map
Starting with "[" -> it's a list

 

[Star-Dust]

if the label/tag name is a number it generates this error. the outer braces should be added

If hj.Success Then
  If ht.GetString.StartWith("{") then
      Dim gs As String = ht.GetString
  Else
      Dim gs as String = "{" & ht.GetString & "}"
  End If

  Log(gs)
  Dim parser As JSONParser
  parser.Initialize(gs)
End if

Thank you all
The problem was [solved] by this way
ِAs Star-Dust & KMatle said

ht.GetString.StartWith("{")
