Every time I try to trigger the action the request response is 400 Bad Request. Configuration is done via the editor of the containing page. Do I have to allow something special somewhere in the configuration or does anyone has any idea how to fix this?
Nothing special is required. I can confirm that an action parameter group configured with a toggle action works just fine. The problem is somewhere in the rest of the configuration which you have not shown.
Is there more to this error?
What is the the yaml result of the page configuration?
@JustinG Thank you for your effort. To answer your question I was just about to collect the information. As I tried to reproduce the Bad Request the widget seems to work out of a sudden. Very strange, I didn’t change anything in the meantime.
