Can I View the Playwright or Puppeteer Code in Test Mode to Verify Functionality?

Sure, happy to help.

Have you narrowed down exactly which action is failing to find the selector?

Meaning, is it typing into email field or password field or is it the actual submission button that’s failing?

I can’t even get it to login. For example, I will use the css #mail and #password locators and it will timeout looking for the locator to even type the credentials in.

I must have tried this over 50 times with different locators and both in puppeteer and playwright

Perhaps try running one action at a time instead of all three to help narrow down which is the issue

Good idea
