Invalid clickthrough error showing up on log

My Database type and version is: 5.7

Your problem
My problem is:
I’m noticing these errors in the log. I’m not sure if it’s safe to ignore them or not or what it means. I have about 4 of these errors in two weeks, it’s recurrent. Can I safely ignore it?

These errors are showing in the log:
