ixnetwork-restpy 1.1.5 with IxNetwork 9.20 error with InstanceId is not a string for field stack operation

[johcheun]

Upgraded from ixnewetork-restpy 1.0.48 to 1.1.5. Same script worked on IxNetwork 9.20 with 1.0.48 but not 1.1.5.

File "/usr/local/lib/python3.7/site-packages/ixnetwork_restpy/connection.py", line 461, in _process_response_status_code
raise BadRequestError(message, response.status_code)
ixnetwork_restpy.errors.BadRequestError: InstanceId is not a string

Hi John, We have a HF for this issue. This HF is for ixNetwork 9.20. This should be applied on ixNetwork API Server machine. link:
https://downloads.ixiacom.com/support/downloads_and_updates/eb/HF001150/IxNetwork9.20.2112.6.001150.exe

@therkong Looks like above link is now access restricted. Also since our ixNetwork API server machine is running in native IxOS, and in kvm qcow2 environment, where both are Linux based. How to apply above HotFix as it's Windows format .exe ? Thanks!

[therkong]

What is your ixNetwork activation code? Can you send email to support.ix@keysight.com and cc theresa.kong@keysight.com with problem description? I will open a support ticket and get you the HF that you need for Linux OS
