Currently, I got the error Error: No more than 12 Serverless Functions can be added to a Deployment on the Hobby plan. Create a team (Pro plan) to deploy more. Learn More: https://vercel.link/function-count-limit in a branch, pushed to Vercel. I once had the api folder in the pages directory, but I've deleted it, so there's no serverless function in my project anymore. Yet I got the error.

Please is there a way to resolve this issue without upgrading the plan?
