Worker is canceled when exporting with PDF MIME type

Hello! My worker is canceled when making a Google Drive export PDF API call. The odd thing is the worker is only canceled when triggered via a webhook call (POST) from the Google Drive watch API and changing the mimeType for the export request to text/plain instead of application/pdf; then the export completes successfully. Invoking the worker with a POST request via Postman or GET request, the worker exports the file successfully with the application/pdf mime type. Is there a limitation with Workers and exporting PDFs via the Google Drive API?

Please let me know if there’s any additional detail I can provide, and thanks in advance!

I managed to get the Google Drive export PDF API call working by passing the request Promise to waitUntil.

export default {
  async fetch(request, env, ctx) {

         fetch(`${fileId}/export?mimeType=application/pdf`, ...)
         .then(response => response.blob())
         .then(blob => env.BUCKET.put("file-name"), blob)


      return new Response(...)


Using async/await without waitUntil is still causing the worker to be canceled. Hope this will help someone looking to export files via the Google Drive API and Workers.
