How can I define a security scheme and set into @useAuth()?

[PiliNi]

I'm trying to implement a spec similar with OpenID Connect by TypeSpec.

@useAuth(OpenId)
namespace PetStore;

model OpenId {
    type: AuthType.openIdConnect;
    openIdConnectUrl: "https://server.com/.well-known/openid-configuration" 
}

I got an error when I used @useAuth() by myself define model.

Emitter "@typespec/openapi3" crashed! This is a bug.

Hey @PiliNi this is something that is not supported today as we only had a fixed set of known authentication types. I filed this issue to resolve that #2774.

There is 2 parts to this:

1. is adding support of openid type as this is something supported in openapi3
2. what should we do if we get a custom scheme we don't know about. Crashing like that is definitely not acceptable.
