17 occurrences over the last 90 days in our error log. Always this token key in all cases.
Likely an upstream issue but need to first understand what this means and if there is something to fix or to suppress.

After looking at Apache access logs I found inaccessible `T167243` due to that error.
I assume all 17 occurrences come from this same issue/ticket.
Steps to reproduce:
* `UPDATE maniphest_task SET description = (UNHEX("606060642001335A2C606060")) WHERE id = 1;` and go to `T1`
