If you check the documentation for the capture2 method, you will see that it doesn't accept a stdout_fh argument.

capture2 starts the remote command, and captures any output it sends to stdout and stdin until it exits. Under the hood, it also calls waitpid, and the return code from the remote process can be inspected afterwards, just looking at $?.
