@creydr sorry if this is a dumb question, I still don't 100% understand the full OIDC flow. In this code, why do we fail if we can't get a JWT, instead of just sending an event without an authorization header?

I see it as a contract between the caller and the dispatcher here. When the caller set an oidcServiceAccount (via the WithOIDCAuthentication(sa) option), we assume that they want to use authentication. If we fail to request a token then, then we should report this back to the caller IMO.
