"List of contributors" empty after upgrading to OJS 3.2

Since upgrading OJS to 3.2.1.2, the contributor list for all articles (published and unpublished) is now blank. While this can be manually corrected for the yet-to-be-published articles, the metadata for the published articles cannot be edited (short of versioning). Any advice as to how this has happened and how I can remedy it would be appreciated.

This seems very similar to [Solved] Some contributor list articles disappear after upgrading from ojs 3.1.2.4 to 3.2.0.2 - #11 by asmecher, with the fix apparently included in OJS 3.2.1. I’ve only encountered this issue since upgrading to 3.2.1.2, however.

Solved by manually updating the author database to include publication_id values. See: [Solved] Some contributor list articles disappear after upgrading from ojs 3.1.2.4 to 3.2.0.2 - #18 by ji_farquharson
