Getting missing value returned from Applescript

I have a couple of Applescripts I want to run in Keyboard Maestro. When I test them to run them in the Script editor, I get a missing value returned in the console.

Here is one of my scripts:

tell application "BetterTouchTool"
	execute_assigned_actions_for_trigger "070EFD1D-BFAB-41F9-8352-3B1F7BE6D9FE"
end tell

Not sure what I am doing wrong unless this is restricted in the trial version.

Same here! Trying to run AppleScript from iTerm2 to toggle BetterTouchTool Touch Bar.

tell application "BetterTouchTool"
	trigger_named "Toggle BetterTouchTool Touch Bar"
end tell

get_trigger "6F85690F-1DC7-4C5D-B7F2-CCAD141D5BE3" returns

  "BTTTriggerType" : 643,
  "BTTTriggerTypeDescription" : "Named Trigger: Toggle BetterTouchTool Touch Bar",
  "BTTTriggerClass" : "BTTTriggerTypeOtherTriggers",
  "BTTPredefinedActionType" : 188,
  "BTTPredefinedActionName" : "Toggle BetterTouchTool Touch Bar",
  "BTTTriggerName" : "Toggle BetterTouchTool Touch Bar",
  "BTTEnabled2" : 1,
  "BTTAlternateModifierKeys" : 0,
  "BTTRepeatDelay" : 0,
  "BTTUUID" : "6F85690F-1DC7-4C5D-B7F2-CCAD141D5BE3",
  "BTTNotesInsteadOfDescription" : 0,
  "BTTEnabled" : 1,
  "BTTModifierMode" : 0,
  "BTTOrder" : 0,
  "BTTDisplayOrder" : 0

Same happens with trigger_action "{"BTTPredefinedActionType":101}" (101 is ToggleBTT)

@Andreas_Hegenberg any ideas here?
