Acceptance criteria

• No errors should arise from interacting with the selected Search Funnel metrics on the Site Kit dashboard, regardless of the zero or gathering state for either Search Console or Analytics
  • This was already fixed for the UA version in Potential error in Search Funnel when GA is in a gathering state #6587, so this issue is specific to the GA4 version of the dashboard

Implementation Brief

• N/A.

Test Coverage

It might be worth retesting this once the PR for #6623 has been merged...

This looks like the same issue that we had in the UA version in #6587, it looks like the fix there didn't get ported to the GA4 version though as mentioned in the IB (https://github.com/google/site-kit-wp/pull/6606/files).

[aaemnnosttv]

Taking a closer look here, this seems to be more about the zero state rather than gathering, which seems to work correctly. Could be #6623 is related here as well, but we can at least provide the AC.

FYI @eclarke1 I've scheduled this for Sprint 99 as we've flagged it as a known issue for Bug Bash: https://app.asana.com/0/1204237371873197/1204290577888659/f

[techanvil]

I've checked this one, and can reproduce the error on current develop. Switching to the PR for #6623 does fix it. I'll hold off until that PR is merged, have another check and then send this over to QA for a confirmation.

[techanvil]

As the PR for #6623 has now been merged, I've checked this on develop and the error no longer occurs. Sending over to QA for a confirmation check.

Thanks @techanvil – once confirmed that this is no longer an issue, we can close this as a duplicate since nothing was actually done against this issue.

QA Update ⚠️

@techanvil @aaemnnosttv

I set up Analytics on InstaWP site. Verified analytics status after 2 days but still Analytics showing under gathering mode if dashboard view set to GA4. Can we determine in how many days Analytics move from gathering to zero data state by default in case of GA4 property ?
It will help us to determine if it is correct as per time set for GA4 property or it is a potential issue of analytics not moving from gathering to zero data state.

QA Update ✅

• Tested on dev environment.
• Verified on 3 day older site.
• Now fatal error is not showing on clicking engagement rate and unique visitor from search data when site is in zero data state.
• Verified on both main and entity dashboard.
