I thought this was a dupe of https://github.com/GoogleChrome/lighthouse/issues/1191, @brendankenny was going to look into this to make sure.

For kicks, can you shoot us the URL you're testing against?

[nirgn975]

@ebidel It was https://lifelongstudent.io

[wardpeet]

@nirgn975 do you have this every time?
Extension got through just fine (downloaded from chrome store)

[brendankenny]

I also can't reproduce this in the 1.3.0 extension for this URL or http://projectnovus.autodesk.com/staging.html as mentioned in #1197

I am running Chrome 57, though, and I notice all the bugs so far are using m55. Anyone have Chrome 55 to try? The URL spec is still in progress, so it's possible this was a corner case the URL constructor in Chrome was patched to handle.

I'll download a build of m55 tomorrow if no one else has gotten to it.

[nirgn975]

@wardpeet Yes, I run it 3 times by now. The extension was already installed, I saw it was update itself and try to run it on my website (yesterday I run the old version and it was fine). I didn't close the browser from yesterday, and didn't press on anything to update the extension.

I'm on MacOS. I can try to close the browser and open it again or to uninstall and install it again from Chrome Web Store.

[brendankenny]

I can try to close the browser and open it again or to uninstall and install it again from Chrome Web Store.

I doubt those things would improve matters. It's almost certainly our bug.

Would it be possible to copy some of the console log from Lighthouse into this issue? It would be very helpful if the URL it was trying to parse was in there.

It's a little awkward to get to because this is an extension, but you can access by navigating to chrome://extensions/, clicking the "Inspect views: background page" link under Lighthouse to open up DevTools, going to the console panel in devtools, then running the Lighthouse extension as you were. The log should output to the console as LH runs.

Hopefully in there at the end is the exception and the URL it was trying to parse (something similar to the message Eric got in the CLI form of this bug in this screenshot: https://github.com/GoogleChrome/lighthouse/issues/1186#issue-196802133)

@brendankenny I save the log as txt, hope it's okey.

I wasn't able to repro on http://projectnovus.autodesk.com/staging.html using Chrome mac 55.0.2883.95.

However, the URLs that in the date.now audit triggers look like suspects from https://github.com/nodejs/node/issues/10306...if you take "between 4-9 digits" as meaning that it can be anywhere in the URL.

[Janpot]

@ebidel no, it's only when the first segment of the hostname is a number

[wardpeet]

@nirgn975 Is it possible to give me your timezone :) and time of testing (local time). Also did you have turned off any audits?

[wardpeet]

i'm on to something :)

[nirgn975]

@wardpeet Of course, my time zone is UTC+2, and I was testing it at around 7:40 (AM).
No, I didn't turned off anything.

[wardpeet]

Will be fixed in next release 1.3.1

[pastelsky]

I'm, on v1.3.2 and still getting this error!

[nirgn975]

@wardpeet I have updated to 1.3.2 and I think I'm still getting the same error (log.txt)

[ebidel]

@nirgn975 proper++ fix is in https://github.com/GoogleChrome/lighthouse/pull/1288. Going to have to wait until after the holidays to make a new release. Thanks for your patience!
