AppDaemon - refuse to start

1

I upgrade to AppDaemon 4.2.1 from some old 4.x.x version and not starting .
it stuck in the Starting Dashboards step and can’t find reason ,
probably my previous configuration break up with 4.2.1
but can’t see where:

Hi @Avi_Cohen ,

If no namespace is specified, then it will use default. The error you are getting is because you have 2 plugins (HA and MQTT) with same namespace.

Recommended solution:
Change the namespace of the MQTT to namespace: mqtt. However, when you go to use that plugin in code, you will need to specify the mqtt namespace. If no namespace is specify in code, it will use the HA plugin.

Regards,
Xavi M.
