I’ve started getting the following error every time my check runs:

No snapshot found for this check

The “recommended actions” has no suggestions - it provides the following details of the exception:

Error in invocation of dom.openOrClosedShadowRoot(HTMLElement element):

This monitor has been running for many months without any issues so I’m not sure what changed. I’m using the Chrome plugin Distill Web Monitor
I checked the permissions on the extension - it says “allow this extension to read and change your data on all sites you visit” - “on all sites”

If I set it to run every 10 seconds, I can see the tab open, and think and then close - and then the error message updates. The extension doesn’t show any changes. If I go to the watchlist and manually view changes - the webpage that shows up, is not the one that I am monitoring? It is a different popup window that is reached by clicking a link on that site.

What else can I do to troubleshoot this?

Thank you!

EDIT: I’m on version 3.11.4 of the plugin

version 3.11.4 has a bug where selections containing svg elements throw this error related to dom.openOrClosedShadowRoot. a quick workaround for this issue is to exclude svg elements from selection.

version 3.11.6 has been uploaded to the chrome webstore this week and is currently under review. it should be released within a day or two. if you are using the desktop app, the version 3.11.6 should be available for update or download immediately.

version 3.11.6 has been released publicly.

Thank you! I have updated my plugin, and I no longer see that error! I will need to wait till the page changes, to see if it will pick up the right page or if it is still picking up a different popup - but this is much better!
