Sending GCode via the new Home Assistant Action System is Broken

[Cynopolis]

Home assistant recently updated all of their "services" to "actions" and I suspect that broke the send_gcode service that is provided by this integration. It would be nice to get that updated and working again. Everytime I try to call the service I just get the error Failed to perform the action duet3d.send_code. Unknown error

This is the yaml for the action I'm performing:

action: duet3d.send_code
data:
  gcode: "M112"

Home Assistant Version Info
Core: 2024.9.1
Supervisor: 2024.09.1
Operating System: 13.1
Frontend: 20240906.0

FWIW, I just did the following code and it worked/set my hotend to 100C.

action: duet3d.send_code
metadata: {}
data: {gcode: "M104 S100"}

That's odd. I thought the missing curly braces might be the problem but I got the same failure even when I copy/pasted your code directly.

Ah, it looks like my initial guess was off. I took a look through my debug logs and found this:

So it appears this is an authentication error which would explain why @micaheli was able to get their printer to work and I couldn't. I'm not sure why it's failing to authenticate though. My printer is set up to have a password, but that has been given to this integration.

To complicate things further, I also noticed that the printer will correctly respond about 1/5 times. It will fail to respond if several commands are sent within a few seconds of each other.
