Why Does Cloudflare Pages Hate My PDFs? A Mysterious 500 Error Awaits Your Genius!

Hey everyone, I’m scratching my head over a stubborn issue with Cloudflare Pages and Nuxt 3’s serverless API. I’m trying to process PDFs using pdfjs-dist, but I keep hitting a 500 error. The import import * as pdfjsLib from 'pdfjs-dist/legacy/build/pdf.js' doesn’t seem to play nice in this serverless environment, and even my workaround isn’t cutting it. Here’s the error I’m getting: 
{
  "url": "/api/extractPdfText",
  "statusCode": 500,
  "statusMessage": "",
  "message": "Falha ao processar o PDF: Erro no processamento do PDF: No such module \"chunks/routes/api/pdfjs-dist/build/pdf.mjs\".",
  "stack": ""
}
{
  "url": "/api/extractPdfText",
  "statusCode": 500,
  "statusMessage": "",
  "message": "Falha ao processar o PDF: Erro no processamento do PDF: No such module \"chunks/routes/api/pdfjs-dist/build/pdf.mjs\".",
  "stack": ""
}
Here’s what I’ve tried so far: Switched to a dynamic import with a static path: 
 
const pdfjsDistPath = 'pdfjs-dist/build/pdf.mjs';
const { GlobalWorkerOptions, getDocument } = await import(pdfjsDistPath);
 
const pdfjsDistPath = 'pdfjs-dist/build/pdf.mjs';
const { GlobalWorkerOptions, getDocument } = await import(pdfjsDistPath);
Dropped the workerSrc config since it’s not needed in this setup. Still no luck! Has anyone tackled pdfjs-dist in Cloudflare Pages’ serverless world? Is there a secret sauce to making this work, or am I missing something obvious? Any help would be awesome—thanks in advance!
