Heartbeat panics when connection is lost #15

Open berk-can opened 3 years ago

berk-can commented 3 years ago

Hi there, I am using gotalk with linux devices and we sometimes reboot these devices, and at one time we encountered an error with panic in app

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0xa64872]

goroutine 3183863 [running]:

Is there a way to recover from panic
