I created Azure AI Services and referring the Cogntive services and its key in the configuration, when I execute the code, I am getting below error.

Error:

HttpResponseError: () Skillsets require a valid 'all-in-one' Cognitive Services key. Provided key is of type AIServices.S0

Solution/Configuration details:
