Fails to navigate on a non-.com #33

Closed thebetterjort closed 6 years ago

We have an internal site that I'm trying to grab PDFS from on the fly. The app works fine on any public url, but not on our internal.

I'm not sure why this happens. You could try to use ignoreHttpsErrors=true query parameter.

You can also try starting it with HEADED=true npm start. This will spawn visible Chrome window when request is done. Note: All requests will return with 500 internal server errors because PDF rendering is not supported in headed mode in Chrome. https://github.com/GoogleChrome/puppeteer/issues/576. From the chrome UI, you could see what's happening.

HEADED env var was removed and DEBUG_MODE added. So you could try DEBUG_MODE=true npm start. It will also leave the browser open after a request.
