The quick answer; nothing to worry about and nothing you can do about (unless you are a developer);
This error occurs when one of the user interfaces tries to do something and it goes wrong; the most common culprit appears to be the iOS app (which for me is causing this error reliably), but other user interfaces reportedly can cause this error too.
If you search the forum, you will find that this error is around for a long time, but does not have any impact on functionality.

PS: it will help in future to make your title clearer: How to ask a good question / Help Us Help You

Many thanks :slight_smile:
I will read through the link you mentioned!

@anon71383850 glad it helped; if this explanation worked, you can mark this post solved; this will help others
