Next js Fast API . A Serverless Function has exceeded max size 250mb

[suntochukwu]

Summary

I’ve deployed my project and get a cryptic error:
Error: A Serverless Function has exceeded the unzipped maximum size of 250 MB. : Troubleshooting Build Error: “Serverless Function has exceeded the unzipped maximum size of 250 MB”

-No information as to which function in particular .

I’ve added outputfiletracing to the next.config- don’t know which paths to exclude because i can’t see where the issue is. The log on build is:

./components/ui/related_articles.tsx

My config file:

const withBundleAnalyzer = require('@next/bundle-analyzer')({

});
const nextConfig = {

Yes that’s where the serverless functions are stored.

My next js directory looks like:
api
|->pycache(folder)
| |->index.cpython39 etc
| -index.py
app
|->aboutus (folder)
| |->page.ts
|–> other_pages(folder)
|->pages.ts
Index.py is where all the endpoints are, it’s just standard endpoints:

import asyncio

app = FastAPI()

leaderboardsdata = {}
@app.get("/", status_code=status.HTTP_200_OK)
def yapa():
    return {'hello' : 'wanderer'} 

def format_date(date_string):
      try:
        dt = datetime.fromisoformat(date_string.replace('Z', '+00:00'))  # Handles 'Z' timezone
        return dt.strftime("%B %Y")  # Formats as "Month Year"
      except ValueError:
        return None  # Or handle the error as needed

//more endpoints..

Can anyone help with this? I need to deploy this application asap and this issue is ridiculous; no clarity at all.
