Works, for me:
Maybe you tried too early, before the first written answer. Error means that there is no data, no replys too.
It was a bit of my mistake. I did not predict that there could be no answers on the new stream. My application then displayed a "no data" error.
I corrected the error, now it should not confuse the user:
"No data, check provided link or wait for the first reply on chat."
I added to the instructions:
4 - If there are no responses in the chat, you may see a "no data" error. It's normal, wait for the first answer, or write something yourself like: "Hello everyone." Even if there is error, the TTS system should read the first message after a while if it appears.
@indy8phish thanks for helping me understand this problem
