[Evergreen-general] Inconsistent White Screens with Hatch

Wed Nov 8 07:25:43 EST 2023

By the way 'preload pages' was not an option in Chrome on my Mac yesterday.  Today it is.

Thanks for the detailed reply, Dan. All good information to have.

We're going to try Garry's solution and see if it works: "Try going into Chrome settings -> performance and turn off preload pages." So far so good, but it's only been a few minutes.

Hi John,

We've also encountered intermittent Hatch issues recently that are exactly as you describe.

We had two reports of this behavior the week of October 23. At the time, we were also on 3.7.3. Both libraries that were affected encountered incomplete page loads only when accessing bookmarks (such as for Checkout, Item Status, etc.) while Hatch was enabled. If the affected libraries reloaded a page after the incomplete page load OR if the bookmark was clicked twice in quick succession (innovative!), it would load completely without fail. If Hatch was disabled or if links were accessed using the links within Evergreen's interface, the page loaded just fine -- no workaround necessary.

I took a look at the extensions logs on an affected machine. Hatch is exhibiting the same type of behavior as it had in late 2021 with these incomplete page loads, where the port for the tab is disconnected and Hatch does not respond to the message it is sent.

We upgraded to 3.11.1 at the end of last week, so I wanted to wait to see if the upgrade somehow resolved the Hatch-related problems before trying to figure these out, especially since two of our libraries were affected. Unfortunately, at least one of the libraries is still encountering problems with bookmarks. And, funny enough, we've had two more libraries report what sounds like the same problem within the past hour or so.

Since the upgrade to 3.11, we've also encountered another Hatch-related issue. I'm not sure if it's the same root cause, but I figured I'd mention it: With Hatch enabled, opening Evergreen's home button in a new tab results in being asked to register a workstation. This behavior isn't encountered when Hatch is disabled. It's only encountered when opening the splash page via that home button in a new tab; opening in the same tab works fine.

So, +1 to the idea that something has recently caused Hatch to start misbehaving.

Hello!

Historically we've found that bad installations of Hatch can lead to blank/white screens in Evergreen, and reinstalling Hatch usually resolves this.

However, over the last week or so, we've started to receive reports of blank/white screens that we cannot seem to resolve. The problem is slightly different from historical reports in that the white screens do not appear every time, and they are more likely to appear when accessing a web client page from a bookmark than within the client. Refreshing a blank page can sometimes force it to load correctly. It's the inconsistency that's making this hard to nail down.

Has anyone else run into this issue and have you had any luck in resolving it? We've gotten a total of 5 reports over the last week or so.

Some information about our setup:

  *   Running Evergreen 3.73 plus some newer features
  *   Affecting (at least) Chrome 119.0.6045.105 and 119.0.6045.106
  *   Affecting (at least) Hatch version 0.3.2 and 0.3.3.

And what we've tried:

  *   Clearing cache
  *   Updating/recreating bookmarks
  *   Updating Chrome
  *   Updating Hatch
  *   Reinstalling Hatch
  *   Clearing site settings and cookies
  *   Removing eg.hatch.login_keys from in-browser preferences

The only way we've found to stop it completely is to disable Hatch, which some of our libraries rely on heavily.

When a page fails to load, the console seems to hang up on this message:

Anyone have any thoughts or suggestions?

Thank you!

John
