Drupal Module 3.8.5: Fatal Error Viewing Non-Translatable Entity References Fixed
A single fix in the Opensolr Search Drupal module, released as 3.8.5 on drupal.org.
01 What was broken
Viewing content that references a non-translatable entity could trigger a fatal error. Sites that mix translatable and non-translatable entity types were the ones affected, and the failure happened on view rather than at save time.
Version 3.8.5 fixes it. Update through Composer or from the project page on drupal.org.
