I recently upgraded my Python from 3.6 to 3.8 and now I am receiving an error when running my scripts.
BlueZone version is BlueZone Mainframe Display v7.1.4.2796 (64-bit)
Python version is 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)]
My company limits what Python modules I can use. I was able to get the below code to work in Python 3.6
from comtypes.client import CreateObject
bzhao = CreateObject("BZWhll.WhllObj")
bzhao.Connect()
bzhao.WaitReady(10, 1)
When I run the above code I now get the below error.
Traceback (most recent call last):
File "C:\Program Files\Python38\lib\ctypes\__init__.py", line 123, in WINFUNCTYPE
return _win_functype_cache[(restype, argtypes, flags)]
KeyError: (<class 'ctypes.HRESULT'>, (<class 'comtypes.BSTR'>, <class 'comtypes.automation.tagVARIANT'>, <class 'comtypes.automation.tagVARIANT'>), 0)
During handling of the above exception, another exception occurred:
