Azure OpenAI Error With Vision Tool

Hi,

I’m unable to get Auzre OpenAI working. I’ve followed the tutorial exactly. I get this error:

I encountered an error while trying to use the tool. This was the error: The api_key client option must be set either by passing api_key to the client or by setting the OPENAI_API_KEY environment variable.
Tool Vision Tool accepts these inputs: Tool Name: Vision Tool
Tool Arguments: {‘image_path_url’: {‘description’: None, ‘type’: ‘str’}}
Tool Description: This tool uses OpenAI’s Vision API to describe the contents of an image.

Please help.
