Unrecognized verb: %s

Error message

Unrecognized verb: %s

What it means

PhabricatorConfigIgnoreController renders the confirmation dialog for setup-issue actions and accepts only the verbs 'ignore' and 'unignore' decoded from the request. Any other verb value falls through to a hard Exception ('Unrecognized verb: %s'), producing an error page instead of a dialog.

Solutions

1. Use only 'ignore' or 'unignore' as the verb segment: /config/issue/<issue-key>/ignore/.
2. Reach the dialog from the setup issue's own page (/config/issue/) so links are generated correctly.
3. If a custom integration links here, generate the URL from a whitelist of the two known verbs.

Example fix

# before
/config/issue/db_LEGACY_UTF84/ignored/
# after
/config/issue/db_LEGACY_UTF84/ignore/

// When generating links to setup-issue management, whitelist the verb.
$verb = idx($request->getURIData('verb'));
if (!in_array($verb, array('ignore', 'unignore'), true)) {
  return new Aphront400Response();
}
$uri = '/config/issue/'.$issue_key.'/'.$verb.'/';

When it happens

Trigger: Hand-editing the URL /config/issue/<issue-key>/<verb>/ with a typo or arbitrary word; custom dashboard links or extensions constructing this URL with a wrong verb; stale bookmarks after a verb rename.

Common situations: Almost exclusively reached by manual URL editing or buggy custom navigation, since the UI only generates 'ignore'/'unignore' links from the setup-issue page.
