Hallo liebe Community,
als stiller Mitleser hat sich bei mir nun doch nach einem Neuaufsetzen meines Systems ein Fehler eingestellt, bei dem ich selbst nicht weiter komme.
Der Adapter fullybrowser ließ sich wunderbar installieren und konfigurieren. Nach einem Aufruf von

iobroker stop

und anschließendem

iobroker start

kann der Adapter aber nicht mehr gestartet werden, weil ihm ein Module fehlt:

Schaut man sich nach dem Stoppen von iobroker in der Console den Pfad des Adapters an, fällt auf, dass hier einiges fehlt:

pi@ioBroker-RasPi:/opt/iobroker/node_modules/iobroker.fullybrowser $ ls -l

Kurioserweise lässt sich das Ganze beheben, indem der komplette Adapter samt Instanz über die Adminseite im Browser gelöscht und anschließend in der Konsole (und nicht über die Adminseite!) mit

pi@ioBroker-RasPi:/opt/iobroker $ npm install iobroker.fullybrowser@2.0.8 --production
+ iobroker.fullybrowser@2.0.8
removed 7 packages and updated 1 package in 11.605s

26 packages are looking for funding
  run `npm fund` for details

installiert wird. Legt man nun eine Instanz an, kann man wieder seine Daten konfigurieren und bis zum nächsten Neustart läuft der Adapter.
Jemand eine Idee und/oder Lösungsvorschläge?

PS: Bevor jemand fragt
