homebridge-hue: [Hue] Error: Cannot add a bridged Accessory with the same UUID as another bridged Accessory

I have upgrded to node 12.13.0 which went thru just fine., however I now get an error towards the end of the log wenn homebridge-hue has listed all the accessories as follows:

[11/8/2019, 23:59:01] [Hue] Error: Cannot add a bridged Accessory with the same UUID as another bridged Accessory: 4dbf54e4-c8d5-4d39-b4bd-8d3b87acbfde at Bridge.Accessory.addBridgedAccessory (/usr/local/lib/node_modules/homebridge/node_modules/hap-nodejs/lib/Accessory.js:268:13) at Server.<anonymous> (/usr/local/lib/node_modules/homebridge/lib/server.js:416:24) at /usr/local/lib/node_modules/homebridge/node_modules/hap-nodejs/lib/util/once.js:16:19 at /usr/local/lib/node_modules/homebridge-hue/lib/HuePlatform.js:282:5 at Function.then (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/_ext.js:65:13) at Deferred._settle (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/deferred.js:93:26) at Deferred.resolve (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/deferred.js:138:15) at Function.<anonymous> (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/ext/promise/catch.js:29:4) at Deferred._settle (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/deferred.js:93:26) at Deferred.resolve (/usr/local/lib/node_modules/homebridge-hue/node_modules/deferred/deferred.js:138:15)

I deleted the accessories folder, rebooted the raspi, restarted homebridge a few times. Nothing seems to help. I’d appreciate any hints.
