After working on an app and successfully tested it locally I was happy to push and deploy it to production. But in production I am getting an error trying to verify a registered user account. The error:

504: GATEWAY_TIMEOUT

After doing some searches, I found out that my app deployed to Vercel can only be processed for 10 seconds. My question is - how to reduce the amount of time API route takes to respond. The app also uses Prisma's Accelerate to help with connection pooling, but what baffles me is why it takes longer than 10 sec to redirect user back to the app from clicking a link in the email.

Can setting up Turbopack help resolve this, can adding connection pooling such as this help:

const prisma = new PrismaClient({
  // Configure connection pooling options here
  // For example:
  //   datasources: {
  //     db: {
  //       max: 20,
  //       idleTimeoutMillis: 10000,
  //     },
  //   },
}).$extends(withAccelerate());

better yet has anyone ran into similar issues, and how were they able to resolve it?
