Hi openhab community,
after years of reading in this community and finding tons of useful information here, i now came to the point of needing to ask for help myself. I hope we can find a solution for my problem together.
I added a Amazon Echo Show to my openhab setup, to use it as a smart music alarm clock. Setup was quite easy, except for one thing. To set the alarm times dynamically, I wanted to send a command (with the same promt as when you use the voice input) to the echo. Sadly this doesn’t work, I get the following error in the log:
2022-01-25 19:24:45.927 [ERROR] [nal.common.AbstractInvocationHandler] - An error occurred while calling method 'ThingHandler.handleCommand()' on 'org.smarthomej.binding.amazonechocontrol.internal.handler.EchoHandler@88b69c': null

I’m running Openhab 3.2.0, Amazon API is amazon.de, every other Items work as expected. I tried the Echo Control Plugin included in 3.2.0, and also Version 3.2.10 from here (which fixes the Websocket Bug, but not my issue).
Below you can find the item/thing config and the jython rule I used to test, but its nothing too extraordinary I guess. Thanks in advance for your help!
Regards
Item
