App not showing correct user's data

(edited)

Hello everyone! I’ve been working on my first mini-app called FrameFlow, which displays user stats from Farcaster. The idea is simple: a user logs in with their Farcaster account—or manually enters their FID—and the app generates a personalized stats card.

I’ve run into a few issues in v0 that I haven’t been able to resolve. I’m currently on Neynar’s Starter plan ($9/month), but some of the data points just aren’t working. For example, if you open the app and enter my FID (17673), it correctly shows my follower and following counts as well as my handle. However, all the other fields either display as zero or show incorrect values.

I’d really appreciate any help in figuring out what’s going wrong. Here’s the link to my mini-app: https://v0-fid-yearbook.vercel.app/

This is also my browser console log when i click on generate card button:

really appreciate you all in advance.

Did you know there's another category dedicated to #v0 topics? A human should be here soon to help, but the answer may already be available even faster in one of these other posts.

Our docs are a great place to start.

From the browser's point of view, all it does is fetch an image (from your og route) and receive the image that already has the incorrect zeroed out data, so there won't be any solutions in the browser console logs

You'll need to look at the server logs which should be here for you (based on your team and project name) https://vercel.com/cryptouii7-7387s-projects/v0-fid-yearbook/logs

Check to see if there are any errors, as zeroed out data could be from other services not connecting
If you don't see any errors, add a console.log(userInfo) right before your return statement in the og URL, and then try again. Each data point on the card will be a variable like <span>{userInfo.accountAge}</span> and you can see by logging userInfo if you're trying to access the wrong property or if the data is just missing

I followed the suggested debugging steps and generated test cards for FID 3 and FID 17673.

I was unable to find the required logging line ([v0] === FINAL USER INFO BEFORE RETURN ===) for either user because the serverless functions are failing early with critical errors.

Here are the specific errors I found in the Vercel logs:

/api/og Endpoint Error:

[v0] FAILED - Registration timestamp is invalid: null

RPC/External Service Error (on /api/get-total-minted):

[v0] RPC endpoint https://base.llamarpc.com failed: An internal error was received.

Summary of Findings:

Missing Data: I cannot provide the onchainActivity values because the API is crashing before it reaches the logging point.
Root Cause: The failures point to a problem with either fetching user registration data (it appears to be null when expected) or a breakdown in the connection to the external Base RPC endpoint.

Please use this information to diagnose the issue. Let me know if you need me to run any different tests.
