Azure OpenAI own data request from PowerAutomate fails "Gateway cannot authenticate upstream services. Please contact Microsoft for help."

Hi,

I'm trying to build an app that uses Azure OpenAI:s chat extensions endpoint https://MYINSTANCE.openai.azure.com/openai/deployments/MYDEPLOYMENTNAME/extensions/chat/completions?api-version=2023-08-01-preview

From Postman it works correctly. But from PowerAutomate it gives error 500 body:

{
  "error": {
    "code": "InternalServerError",
    "message": "Gateway cannot authenticate upstream services. Please contact Microsoft for help."
  }
}

Hi @JoeLAP ,

Thanks for using Microsoft Q&A!!

Do you have any network restrictions configured for this resource?

Thanks

Hi,

Thanks!

I didn't have any network restrictions. But due to having a closer look I noticed the mistake I made in PowerAutomate.

I tried to use the same api-key in body (for embeddings) and header for endpoint https://MYINSTANCE.openai.azure.com/openai/deployments/MYDEPLOYMENTNAME/extensions/chat/completions?api-version=2023-08-01-preview

even though I was using another resource for the embeddings.

Tested and works after changing the correct api-key for embeddings. :)
