I'm new working with NextJs and when trying to deploy my project to Vercel I'm getting the following error:

> 
> Error! The Serverless Function "api/auth" is 50.55mb which exceeds the maximum size limit of 50mb.
> 
> 
> 

I have spent a lot of my time trying to find a proper answer but I didn't find any. Here is the code of the api request I'm making:

```
const { auth: adminAuth } = require("firebase/admin");

export default async function auth(req, res) {
  const tokenId = req.query.token;
  return new Promise((resolve) => {
    adminAuth
      .verifyIdToken(tokenId)
      .then((user) => {
        res.json(user);
        resolve();
      })
      .catch(() => {
        res.status(302).send("Invalid authentication");
        resolve();
      });
  });
}

```

I'll be really grateful if anybody can help me, thanks y'all!
