Amazon EchoControl TextCommand no longer work

SetUp:
RPI 5/SSD - openHAB 4.3.2 - Amazon Echo Control Binding 4.3.2
I’m using the “normal” Amazon-Binding with this test-rule:

rule "alexa TextToSpeach Tower"

 when 
   Item Dummy_3 changed to ON   // Test-Switch
 then
   EchoTower1_TextToSpeechVolume.sendCommand(50)
   EchoTower1_TextToSpeech.sendCommand("Hallo ich bin ein schwarzer Echo Tower")  // 
   EchoTower1_TextToSpeech.sendCommand("ich kann dir etwas erzählen, wenn du willst")  
   EchoTower1_TextToSpeechVolume.sendCommand(0)
// sendCommand(EchoTower1_PlayAlarmSound, 'ECHO:system_alerts_atonal_02')
end

and no problems detected.

Edit:
Have you spotted the other posts regarding the problems with that binding ?
