Hot tip: When you use @inngest in combination with @aisdk, set maxRetries: 0 and add abortSignal and let Inngest handle the retries itself. The issue is that in combination with Vercel, your /api/inngest endpoint may timeout, Inngest sees dropped HTTP request and doesn't know why. These are very annoying situations to debug. Rather, let LLM API request timeout, add log messages and handle the timeout gracefully.
