This task is about MediaWiki's FormWizard extension.
This is a doc comment for the variable configData which has been moved (does not exist where doc appears).
Notes to Developer
This variable has been moved somewhere in the module but this comment is left here.
Either move the comment (if the variable does not have a doc where it was moved in the code) or remove it completely ( if there is documentation for configData already).
You are expected to provide a patch in Wikimedia Gerrit. See https://www.mediawiki.org/wiki/Gerrit/Tutorial for how to set up Git and Gerrit.
