The :input and :output arguments establish stdin/out for the process.
The :pty argument ALSO establishes these.

So, when using :pty, don't use :input/:output.
Furthermore, :pty doesn't take :stream as an argument, just give it T
And afterwards, PROCESS-PTY gives the relevant stream.

I hope that helped a little.  I see that sh complained about not
having a tty, I hope this won't become a problem for you.
