I receivde status code 500 in response as a result of speechSynthesis command to galaxy home mini

Hello,
I’m trying to develop TTS(Text To Speech)Node in Node-RED.
So before i starting develop, I tried API test to my galaxy home mini using postman.
capability.audioVolume.VolumeUp() is working, But capability.spechSynthesis.speak() return Error code 500.

Is there any way to request to speak my device?
