Max, Can you decode this for us?
I'm not Max and maybe he will shed more light on it. I didn't find such
error in our documentation.
Sorry for the late response.
Yi Zhang,
Is it still repro ?
Hi Max
The good news is the NULL pointer cannot be reproduced any more with
4.13.0-rc6.
But I found bellow error on target and client side during the test.
Client side:
