Vercel Eve default OIDC triggers 401s
A developer attempting to connect a custom Next.js frontend to a Vercel Eve agent encountered 401 Unauthorized errors on the `/eve/v1/session` endpoint. This issue occurs because the framework enforces OpenID Connect (OIDC) authentication by default, blocking external client-side calls unless developers explicitly configure auth overrides (such as Clerk, Auth.js, or basic auth) in the agent's channel configuration.
// ANALYSIS
Enforcing strict default authentication prevents accidental API exposures but introduces integration friction.
- –Vercel Eve uses OIDC to enable keyless authentication with model gateways, which restricts cross-origin request options out of the box.
- –Developers must modify the default placeholder auth strategy in `agent/channels/eve.ts` to allow access from external chat interfaces.
- –The learning curve highlights a common trade-off between secure infrastructure defaults and the developer experience of multi-repository or decoupled application setups.
