+---
+
+This patch addresses an issue identified in Backstage when configured with a MySQL database. If an entity of type location
+(e..all.yaml) has more than 70 referenced entities, clicking "Refresh" does not update the referenced entities as expected. This occurs because the TEXT type in MySQL has a limit of 65,535 bytes, which is insufficient to store all the referenced entities, causing the refresh operation to fail.
