Describe the bug

I always find this bug when searching for elements

Dim Elspgsuara = Adb.FindElement("//node[@text='Mulai panggilan suara?']")

for the device

how to solve it if node is null

Steps to reproduce the bug

Dim elEndC = Adb.FindElement($"//node[@resource-id='com.{whatsapp}:id/footer_end_call_btn']")
If (elEndC Is Nothing) Then
    Dim Elspgsuara = Adb.FindElement("//node[@text='Mulai panggilan suara?']") 'bar ic VOICE

    If Not (Elspgsuara Is Nothing) Then
        Thread.Sleep(500)
        KlikTouch("PAG", whatsapp)
    End If

    Dim Elstpaggil = Adb.FindElement("//node[@text='Pilih tipe panggilan']") 'bar ic VOICE

    If Not (Elstpaggil Is Nothing) Then
        Thread.Sleep(500)
        KlikTouch("PS1", whatsapp)
    End If
End If

There could be many reasons. Please provide xml from the DumpScreenString method:

var client = new AdbClient();
var device = client.GetDevices().First();
var screen = client.DumpScreenString(device);
await File.WriteAllTextAsync("node.xml", screen);
