[BUG] Executable path does not exist

[eduardodgdebem]

Environment

• chromium Version: 119.0.2
• puppeteer / puppeteer-core Version: 21.5.1
• Node.js Version: 18.x
• Lambda / GCF Runtime: nodejs18.x

I'm not sure if I'm doing something wrong but very time a try to run puppeteer with "@sparticuz/chromium" on vercel with nodejs18.x it throws "The input directory "/var/task/.next/server/app/api/trpc/bin" does not exist." but locally it throws the same error.

Steps to Reproduce

I just created a nextjs app with trpc and tried to run the following code on vercel

import puppeteer from "puppeteer-core";
import chromium from "@sparticuz/chromium";
import type { HTTPResponse, Page, Handler } from "puppeteer-core";
import { sleep } from "~/helper";

const imgExtensionRegex = /\.(png|jpeg|jpg)$/i;

const scrollToBottomSlowly = async (page: Page) => {
  const scrollHeight = await page.evaluate(() => document.body.scrollHeight);
  const viewportHeight = await page.evaluate(() => window.innerHeight);

  let currentPosition = 0;
  while (currentPosition < scrollHeight) {
    await page.evaluate(() => {
      window.scrollBy(0, window.innerHeight / 10);
    });
    currentPosition += viewportHeight / 10;
    await sleep(5);
  }
};

export const scraper = async (url: string) => {
  if (!url?.length) throw Error("No URL for the download");

  const browser = await puppeteer.launch({
    args: chromium.args,
    defaultViewport: chromium.defaultViewport,
    executablePath: await chromium.executablePath(),
    headless: chromium.headless,
  });
  const page = await browser.newPage();

  const filesMap = new Map<string, string>();

  const downloadOnResponse = (res: HTTPResponse) => {
    const url = res.url();
    if (
      res.request().resourceType() === "image" &&
      imgExtensionRegex.test(url)
    ) {
      res
        .buffer()
        .then((file) => {
          const fileName = url.split("/").pop();
          const base64 = Buffer.from(file).toString("base64");
          if (fileName) filesMap.set(fileName, base64);
        })
        .catch(console.error);
    }
  };

  page.on("response", downloadOnResponse as Handler);

  await page.goto(url);
  await page.waitForNetworkIdle();
  await scrollToBottomSlowly(page);
  await browser.close();
  const sortedFilesMap = new Map(
    [...filesMap.entries()].sort((a, b) => {
      const aNum = +a[0].split(".")[0]!;
      const bNum = +b[0].split(".")[0]!;
      if (!isNaN(aNum) && !isNaN(bNum)) {
        return aNum - bNum;
      }
      return a[0].localeCompare(b[0]);
    }),
  );
  return sortedFilesMap;
};

You'll need to specify the location of the brotli files.

@DoveLanLan I'm with the same issue, how did you solved it?

[Sparticuz]

Make sure you have the correct settings for bundling external dependencies in your next config. If that doesn't solve it, then you probably need to specify the location of the brotli files.
