Unable to Start/Stop HBOT through RPC

[HESSEBO]

Environment: Linux Docker

I am trying start start/stop HBOT through Nodred Flows through MQTT inject node, after connecting both HBOT and nodred to the same topic. I can see HBOT on the logs saying that: ''rpc - could not unpack request message 'data'

My guess that probably my triggering command start/stop is recognized by hbot instance, may be I didn't inject the right command to trigger. I tried the following command on the inject node:

{ "name":"start", "command":"start" } start, stop etc... All didn't work
