As the title states, when I send a message to a muc light room, the following log string is printed and no notification is sent.

I'll add more information if needed

Hi! Thank you for the report.

Did you manage to enable push notifications in the end? From what I see, the error was related to mishandling of the MUC Light host, when a stanza was addressed to a room, and should not affect push notifications. We will fix the error in the logs, but you should still get the notifications. From the configuration you provided, they should be POSTed to "http://172.17.0.4:1080/push/notifications".

Hi! Thank you for your response.

No, I didn't investigate this further due to time related reasons but I'll try again if I'm able to!
