[gatsby-plugin-offline] IOS 13 Safari error `null is not an object (evaluating 'n.announcementRef.current.innerText')`

I got error in Sentry logs, it points to ./.cache/navigation.js in apply at line 177:52

      const pageHeadings = document.querySelectorAll(`#gatsby-focus-wrapper h1`)
      if (pageHeadings && pageHeadings.length) {
        pageName = pageHeadings[0].textContent
      }
      const newAnnouncement = `Navigated to ${pageName}`
      const oldAnnouncement = this.announcementRef.current.innerText // error on this line
      if (oldAnnouncement !== newAnnouncement) {
        this.announcementRef.current.innerText = newAnnouncement
      }
    })
  }

which triggered after 2 consecutive errors in the console InvalidStateError: Service Worker state is redundant

As you can see on last screenshot - there is navigation action from /en/account/transfer, to /en/account/withdraw. Both routes are fully dynamic, and do not pre-rendered at build time.

iOS 13.3.1 Mobile Safari 13.0.5

@madalynrose I can’t create a reproduction, since I got only single error in logs in Sentry in single project from many. I will update gatsby.js to the latest version in all my projects and will look if it repeats in logs

Hi. I’m going to close this now, as we can’t do much to help without a reproduction. If you are able to create a minimal reproduction for this then please do reopen the issue. Thanks!
