Description

Searching for the string Void in the Find feature seems to spin forever.

Scrolling down to the Void type on the left nav bar and clicking it results in an entry in the content pane that looks like it's loading. It takes a minute or so to fail with an error. UCM is totally unresponsive while this is happening.

A query to the API like api/getDefinitions?names=Void responds normally and quickly.

Research direction
Investigate the `/find` endpoint implementation to understand why requesting the `Void` type causes a hang. Look for infinite loops or recursive calls triggered by `Void`. Compare with the working `api/getDefinitions?names=Void` endpoint to identify differences. Check the linked issue comments for any additional context from maintainers.
