Crash on CocoaMQTT

[anhtran2020]

Hi, I'm using CocoaMQTT inside a framework
And sometimes It's crashed in the payloadReady() method
I don't know how to reproduce the crash, but I think when data is [0, 0, 0]

This is my configuration MQTT code:

Hi, any feedback on this issue? What caused it, is it fixed or happens it last release?
Were you able to reproduce it on the last release?
Thanks in advance.

Hi, I tried the data is [0, 0, 0] which is running well in the last version. This issue may be caused by the background thread?
