31922: Stream - WebSocket - URL Schema Not Supported

This error occurs when the <Stream> url uses a protocol that Programmable Voice Media Streams does not support. Twilio connects Media Streams over a wss WebSocket connection, and wss is the only supported protocol for the <Stream> url attribute.

• The <Stream> url uses a protocol other than wss.
• The WebSocket endpoint in your TwiML was configured with an unsupported URL schema.

• Update the <Stream> url so it points to a secure WebSocket endpoint that uses the wss schema.
• Review the url attribute in your <Start><Stream> or <Connect><Stream> TwiML and confirm it is formatted for Media Streams.
• If you need to pass values to your WebSocket server, do not add query string parameters to the url. Use nested <Parameter> values instead.
