When recovering session, frame (FramePublish) topic is empty #563

Closed ltAldoRaine closed 4 months ago

Hello,

I have installed the 2.1.6 version via Cocoapods.

I'm facing very strange issue, it seems like, when opening and closing application very fast, some publish requests are saved in the UserDefaults and then recoverSessionBy method grabs those requests and publishes again, issue is when it's retrieving frames from the userdefaults, data decoding is not happening correctly, there is no value in the topic variable for mqtt version 5.0.

Please check screenshot below

Cocoamqtt sends message with empty topic and MQTT broker rejects it and client is disconnected
