thrift.transport.TTransport.TTransportException: Called read on non-open pipe

I have a connection error. Any suggestions? Thank you

PS C:\WINDOWS\system32> python 'C:\Users\sampng\Desktop\python_script\superset.py'                                      Traceback (most recent call last):

thrift.transport.TTransport.TTransportException: Called read on non-open pipe

My Python script:

import os
import osquery

if __name__ == "__main__":
    # Spawn an osquery process using an ephemeral extension socket.
    instance = osquery.SpawnInstance(r"C:\Program Files\osquery\osqueryi.exe")
    instance.open()  # This may raise an exception

    # Issues queries and call osquery Thrift APIs.
    result=instance.client.query("select * from time")
    print (result)

I believe you should spawn osqueryd process instead of osqueryi. Try this: instance = osquery.SpawnInstance(r"C:\Program Files\osquery\osqueryd\osqueryd.exe")
