Unable to change wifi password

When I try to change the wifi password it returns an error message like this;
Remote Exception: Internal error [‘uci’, ‘-c’, ‘/etc/config/’, ‘-p’, ‘/tmp/.uci-foris-controller’, ‘commit’, ‘wireless’]: command failed (b’uci: I/O error\n’)(’<class ‘foris_controller.exceptions.UciException’>’)
