[Bug]: chat app crashes when using Azure OpenAI service

[stevegbrooks]

Confirm setup

• I have installed the development version of {gptstudio} (pak::pak("MichelNivard/gptstudio")) and tested if the problem remains.
• I have installed the {reprex} and {sessioninfo} packages to be able to run this issue's code snippet pak::pak(c("reprex", "sessioninfo")).

What happened?

When trying to engage in a chat using azure_openai service, the gptstudio::gptstudio_chat() app crashes:

My take on this is that the function ellmer_chat.gptstudio_request_azure_openai is getting the skeleton from gptstudio_request_skeleton.azure_openai(), but that skeleton doesn't have fields for endpoint, deployment_id or api_version for some reason.

I tried it out to just manually add these and then running this ellmer_chat.gptstudio_request_azure_openai works without error.

Thanks for reporting. I'll see if I can get a working version. I now have access to Azure OpenAI so I can test the fix.

[stevegbrooks]

Hi @JamesHWade any update on this? I have a fix that I'm using. Just let me know if you'd like me to send in a PR

[JamesHWade]

A PR would be great. I'd be happy to review and incorporate it in.
