Hello All,

Have tried all the usual suspects and still getting this error. Does anyone know the issue?

Hi @DylanT,

Have you looked into this issue? Could you also share your Python package version and usage image?

Thank you for the quick response, Muhammed.
The Load python script looks to be working & is returning me a python object that is then passed to the invoke python method. But it’s there that it is faulting.

Python package is version 1.6.0, libraries & version below.

Hello @DylanT ,

Please watch the below video. I think that can solve your issue.

Please watch the below vi

No new information from that, unfortunately. Thinking perhaps it is an issue with the post URL referenced for microsoft.cognitiveservices.azure.com/ since there is no exception referenced in the python invoker.

Looks like some upgrading to do.

Hi @DylanT ,

Have you tried out using a Simple Python Program and Checked if it is working ?

Also if possible, Could you share the Python Code used ?
