Connection timeout when fetching endpoint from cron-triggered function

(edited)

I’m encountering an issue with the functions in my app. I have deployed two API endpoints:

•	/api/workflows/cron: This endpoint is triggered by Vercel Cron every minute.
•	/api/workflow/sexecute: This endpoint is triggered by a fetch request from the /api/workflow/cron endpoint.

I’m experiencing a connection timeout error when the /api/workflows/cron endpoint attempts to fetch the /api/workflows/execute endpoint. However, calling the /api/workflows/execute endpoint directly works without any issues.

This is an example of request that has failed ( requestID ): ndnwq-1722688988089-ce9b91505686

Any advice on how to resolve this?

Hi, !

Do you have any more logs that you can share? It'd be super helpful.

I've also linked a helpful resource on error codes.

Use this guide to find specific solutions and insights for common Vercel errors.

And on serverless functions timing out:

Hi, there aren't extra logs.

I can't fetch an api from another api triggered by vercel cron. The only error i get is the one i've linked

Any suggestion on how to move on?

Hi , here's additional logs:

Hi, ! Appreciate your patience with us.

I wanted to also share our recent guide on how to troubleshoot cron jobs in case it's helpful for your usecase.

Thanks!
