Error when attempting to turn on printer via PSU Control

[lightmaster]

Describe the bug
I have OctoDash configured to use PSU Control to turn on the printer when the sleeping Octodash screen is touched. PSU Control is configured to use the sub-plugin "PSU Control - MQTT" to send an ON command to a smart outlet via MQTT. From inside OctoPrint, PSU Control and PSU Control - MQTT work great, successfully turning on the printer when the lightning bolt is clicked and turning it off when the lightning bolt is clicked again. From OctoDash however, all I get is an error message saying that OctoDash could not send some GCode. OctoDash should not be trying to send any GCode at this point, so not sure what its attempting to send or why it's attempting to send some GCode.

To Reproduce
Steps to reproduce the behavior:

1. Configure PSU Control with sub-plugin "PSU Control - MQTT"
2. Attempt to wake printer by touching the screen or sending the custom action [!POWERON]

Expected behavior
Octodash should interact with the PSU Control plugin to send a MQTT command to turn on the outlet the printer is connected to.

Mhhh interesting.The error message might be a bit misleading here, but it's being thrown at the right place. Could you please provide the full error message? The smaller text is the interesting part here :)

Sorry, gmail decided to mark the email about this as spam.

Ok 403 is super weird here. That usually happens when the URL is wrong. Could you for the sake of testing disable the MQTT sub-plugin and check whether the error message pops up again?
