join raises error when exception occurs despite having stop_on_error=False

[iameugenejo]

I got this error after using client.join after calling run_command(..., stop_on_error=False):

  File ".../env/lib/python2.7/site-packages/pssh/pssh_client.py", line 404, in join
    for line in output[host]['stdout']:
TypeError: 'NoneType' object is not iterable

so decided to manually wait for stdout, then I get this error:

  File ".../env/lib/python2.7/site-packages/pssh/pssh_client.py", line 416, in get_exit_codes
    output[host].update({'exit_code': self.get_exit_code(output[host])})
  File ".../env/lib/python2.7/site-packages/pssh/pssh_client.py", line 428, in get_exit_code
    return self._get_exit_code(channel)
  File ".../env/lib/python2.7/site-packages/pssh/pssh_client.py", line 432, in _get_exit_code
    if not channel.exit_status_ready():
AttributeError: 'NoneType' object has no attribute 'exit_status_ready'

The problematic code blocks:

def join(self, output):
    """Block until all remote commands in output have finished
    and retrieve exit codes"""
    for host in output:
        for line in output[host]['stdout']:
            pass
    self.get_exit_codes(output)

def _get_exit_code(self, channel):
        """Get exit code from channel if ready"""
        if not channel.exit_status_ready():
            return
        channel.close()
        return channel.recv_exit_status()

shouldn't above be below?

def join(self, output):
    """Block until all remote commands in output have finished
    and retrieve exit codes"""
    for host in output:
        stdout = output[host].get('stdout')
        if stdout:
            for _ in stdout:
                pass

    self.get_exit_codes(output)

def _get_exit_code(self, channel):
        """Get exit code from channel if ready"""
        if not channel or not channel.exit_status_ready():
            return
        channel.close()
        return channel.recv_exit_status()
