API error responses generated by AbuseFilter and SpamBlacklist have changed, as announced here: https://lists.wikimedia.org/pipermail/mediawiki-api-announce/2019-September/000148.html (relevant task: T229539).
It appears you have special handling for the old responses. It only affects event logging.
extensions/WikiEditor/includes/WikiEditorHooks.php:
300: } elseif ( isset( $errors[0][0] ) && $errors[0][0] === 'abusefilter-disallowed' ) {| Subject | Repo | Branch | Lines +/- | |
|---|---|---|---|---|

| Resolved | matmarex | T232687 Update WikiEditor for changes in AbuseFilter and SpamBlacklist API error responses |
So it turns out that this line doesn't need updating, because it is looking at the error message key rather than the error code, and still works as expected.
However, a few lines below is this:
} elseif ( isset( $errors[0][0] ) && $errors[0][0] === 'spamprotectiontext' ) {…and this actually does need updating – not because of the API changes, but because of https://gerrit.wikimedia.org/r/c/mediawiki/extensions/SpamBlacklist/+/531302.
