Oh, thanks.
  I have found that if my return type is  remote_nonnull_string, the error will be happen, 
but if the return type is int, it works ok.

It's easier to review your code for errors if you post the actual
patches you have written so far.

If you're lucky, your new API won't need you to write any code in
daemon/remote.c, but can instead be autogenerated as part of adding your
new API to src/remote/remote_protocol.x.  But it's hard to see what you
might be doing wrong without seeing your full patch.
