(node:1792) UnhandledPromiseRejectionWarning: Error: Operation not permitted
Hi,
Suddenly I've been getting this error while starting Homebridge app. I have the latest homebridge-broadlink-rm plugin installed (3.6.22). I've been trying to find a solution to this but to no avail. Any help is very appreciated. !
NodeJS version: v10.20.1
