the diff comparator override threw; the column comparator was used instead.

diff.override.throw:*

Raised by

The grid (core)

Since

1.0.1

What happened

The diff-level comparator override threw for a column. The column's own comparator is used instead, so the diff still works, with the default comparison rather than yours.

The fix

The error is attached to the console line. An override may return undefined to defer to the column comparator, which is the supported way to handle only some columns.
