Getting error in Raspberry pi zero w

[s-a-tanjim]

When i run the command i get this error: $ python3 server.py Initializing camera Initializing websockets server on port 8084 Initializing HTTP server on port 8000 Initializing broadcast thread Spawning background conversion process Starting recording Starting websockets thread Starting HTTP server thread Starting broadcast thread Waiting for background conversion process to exit Stopping recording Traceback (most recent call last): File "server.py", line 184, in main() File "server.py", line 170, in main camera.stop_recording() File "/usr/lib/python3/dist-packages/picamera/camera.py", line 1196, in stop_recording self.wait_recording(0, splitter_port) File "/usr/lib/python3/dist-packages/picamera/camera.py", line 1167, in wait_recording encoder.wait(timeout) File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 398, in wait raise self.exception File "server.py", line 165, in main camera.wait_recording(1) File "/usr/lib/python3/dist-packages/picamera/camera.py", line 1167, in wait_recording encoder.wait(timeout) File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 398, in wait raise self.exception File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 267, in _callback stop = self._callback_write(buf) File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 580, in _callback_write return super(PiRawMixin, self)._callback_write(buf, key) File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 921, in _callback_write return super(PiVideoEncoder, self)._callback_write(buf, key) File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 298, in _callback_write written = output.write(buf.data) File "server.py", line 106, in write self.converter.stdin.write(b) BrokenPipeError: [Errno 32] Broken pipe

I used this code in Raspberry Pi 3B+, and it worked well. But in pi zero w, i'm getting error.
