OK most (or all?) of the errors are triggered by this commit:

commit e476577ffd2758cd972189384fe40c12cf3217f3 (HEAD -> preview-10.7-MDEV-26519-json-histograms)

Author: Sergei Petrunia <psergey@askmonty.org>

Date:   Sun Oct 10 11:51:04 2021 +0300

    MDEV-26724 Endless loop in json_escape_to_string upon ... empty string

    Part#3:

    - make json_escape() return different errors on conversion error

      and on out-of-space condition.

    - Make histogram code handle conversion errors.

and are caused by handling the unassigned-character code path
