1. client.Subscribe create consumer
2. delete the topic on the console
3. consumer call Close() close the consumer and panic

panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0xe9fab4]

This is unreasonable. For example, the administrator deletes a user, the user loginout, causing the system to crash

@szmikemai I can't reproduce on my local host.

Can you share more context? client-version, step, etc.
