Google Custom Device Action Giving Error on Raspberry Pi Google Assistant

_x000D_ _x000D_ I'm creating a google assistant on my Raspberry Pi 3 and I'm trying to create a custom device action to eventually open my garage door. All it does is play with an LED at this point in time. Here is my actions.json file: { "manifest": { "displayName": "Garage door", "invocationName": "Garage door", "category": "PRODUCTIVITY" }, "actions": [ { "name": "me.custom.actions.GarageDoor", "availability": { "deviceClasses": [ { "assistantSdkDevice": {} } ] }, "intent": { "name": "me.custom.intents.GarageDoor", "trigger": { "queryPatterns": [ "open the garage door", "close the garage door" ] } }, "fulfillment": { "staticFulfillment": { "templatedResponse": { "items": [ { "simpleResponse": { "textToSpeech": "Okay" } }, { "deviceExecution": { "command": "me.custom.commands.GarageDoor" } } ] } } } } ], "types": [] } But when I run the command I get this error: INFO:root:Transcript of user request: "open the garage door". INFO:root:Playing assistant response. WARNING:root:Error during command execution Traceback (most recent call last): File "/home/pi/assistant-sdk-python/google-assistant-sdk/googlesamples/assistant/grpc/device_helpers.py", line 94, in dispatch_command self.handlers[command](**params) TypeError: gdoor() argument after ** must be a mapping, not NoneType Here's my handler: @device_handler.command('me.custom.commands.GarageDoor') def gdoor(*args): print(args) global g_open if g_open: GPIO.output(18, 0) g_open = 0 else: GPIO.output(18, 1) g_open = 1 I was playing around with the *args to see if it fixed anything - it didn't. I've changed my package names to custom just for privacy. I'm quite confused here. Any help appreciated! Thanks!
