TTS bug - sending no response in hands free mode
❓API❓Voice❓Webchat
When i tried to use the hands free voice input mode on the webchat widget, the flow for some reason tries to send an empty string : ""
This only happens when i try to use the hands-free input for some reason. (The input is being sent to my backend server via an API block)
See the logs below:
