how do we reproduce this? I don't think there's sufficient information for us to do anything with this report?

I've browsed the source code which raised a panic by backtracing your stack message but it seemed unlikely to cause a panic of "invalid memory address or nil pointer dereference" there, I'm afraid that we need more info here, a reproducible code example would be the best, if not, at least share more details and context info at the time.

  1. you have all the permission for run ?
  2. panic: runtime error: invalid memory address or nil pointer dereference} //... this maybe happen if you don't use a pointer correctly

I am sorry that I have not checked the reply for a long time. This is an accidental error in the production system. I am sorry that I cannot provide the fault recurrence code.but today again:
