add recover fix export method panic

Log: add recover fix export method panic

I have multiple issues with this:

1. recover is only really a band-aid to put on panics. Where does the panic you're facing coming from? If it's from the library's code, I would rather fix it itself - can you share the panic trace? If it's from the application code, then you should probably rather fix it there, or at least put the recover there.
2. I would definitely not expose the recover return value to the D-Bus method caller - this could be a system-level daemon exposing information to an unprivileged user.

I can understand why not expose the recover return value to the D-Bus method caller, I'm adding a new server error return . it's from the application code, but export method too many,i can't fix it together . I refer to the GO standard library NET/HTTP in https://github.com/golang/go/blob/bd5595d7fa4eb3e234aabeac554f2ba8f2a95790/src/net/http/server.go#L1834
