Background/timed sync repeatedly fails with "Error: Can't find bookmark for id. at checkForApiError" log messages

[trystero11]

Describe the issue you are experiencing
Background sync operations consistently fail with "Something went wrong" error notifications. The log shows "Error: Can't find bookmark for id. at checkForApiError" messages at the times of failure.

I don't see this failure when I manually click "Update Sync" to force a refresh; it's only the timed/background sync operations that produce it.

I've tried disabling my existing sync and creating a new one; still seeing the same issue.

How can the issue be reproduced?
Allow sync operations to run in the background, I guess.

Desktop browser
Please complete the following information for all affected desktop browsers:

• OS: macOS Sonoma 14.5 and Windows 10 Pro 22H2 (build 19045.4529)
• Browser [e.g. Chrome, Firefox]: Google Chrome
• Version [e.g. v1.5.0]: 126.0.6478.62 (x86_64)

I have Chrome's native bookmark sync functionality disabled.

I also run xbrowsersync in Firefox 127.0; that extension doesn't produce the same background-sync failures, and its log doesn't show the "Error: Can't find bookmark for id." error messages.
