Not-useful error message when CORS disabled but required

[abrenneke]

Which version of LM Studio?

LM Studio 0.3.9

Which operating system?

Mac OS

What is the bug?

When a CORS request is made to /v1/chat/completions and CORS isn't enabled in LM Studio, it spits out an unhelpful error "messages field is required" that is confusing to the user.

To Reproduce

1. Disable CORS
2. Make a request from the browser to /v1/chat/completions with valid data

Hi @abrenneke I would expect that you'd get this message when the request doesn't contain messages.

Can you please share the request that made this happen?

[abrenneke]

Right, the request doesn't contain message because it's a CORS preflight request that's failing:

using httpie:

http options localhost:1234/v1/chat/completions Access-Control-Request-Method:POST Access-Control-Request-Headers:Authorization Origin:http://localhost:8080

Thanks @abrenneke to be sure: things are working, but the error message is annoying? Or is it functionally not working either

[abrenneke]

Things are working, the error message was just confusing!
