Puppeteer error with browser

[leozelion]

I tried using your plugin today, but catch this error by Puppeteer:

Error: Could not find browser revision 782078. Run "PUPPETEER_PRODUCT=firefox npm install" or "PUPPETEER_PRODUCT=firefox yarn install" to download a supported Firefox browser binary.
    at ChromeLauncher.launch (F:\GASUdocs\EXAM\save-answersheets\node_modules\puppeteer\lib\cjs\puppeteer\node\Launcher.js:86:23)

OS: Windows 10 20H2
NPM: 6.5.0
NodeJS: 14.17.1
PowerShell: 5.1.19041.1023

Most likely this is the solution here: puppeteer/puppeteer#6560 (comment)
So, I added this change in your code:

save-answersheets.js
@@ -110,1 +110,5 @@
-    const browser = await puppeteer.launch();
+    const browser = await puppeteer.launch({
+        // Point to existing Chrome install because NPM won't install Chromium
+        // https://github.com/puppeteer/puppeteer/issues/6560#issuecomment-719976065
+        executablePath: 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe'
+    });

And it works fine now. Thank you for this plugin!

Interesting. I haven't seen this yet, but thanks for the tip.

I've just tried things again, and it works without this for me.

And, even though my Chrome exe is in exactly the same place as your, it feels wrong (risky) to me to hard-code this path, if it should work without it. So, I am relucant to make this change in the master version of the code.

However, if anyone else hits this problem, having this issue here might help them work out what to do.

(If anyone else does have this problem, please comment here. If it affects lots of people we will need to do something.)
