Just installed unifi-detect on the Raspberry Pi. When I run the command I get the following error message:

pi@Domoticz:~/unifi-detect $ unifi-detect -c config.json
undefined:1
[object Object]
^

SyntaxError: Unexpected token o in JSON at position 1

The npm version installed is: 6.14.5.

The config file looks like:

{
"unifi": {
"url": "https://192.168.0.25:8443",
"user": "xxxxxxx",
"password": "xxxxxxxxx%",
"idleTime": 60
},
"domoticz": {
"url": "https://unifi:[email protected]",
"deviceMappings": [{
"mac": "xx:xx:xx:xx:xx:xx",
"deviceAlias": "iPhoneReneAtHome",
"switchId": "100"
}]
}
}

What is going wrong? How can I resolve this?
