Argument #9 of EntityDataRequestHandler::__construct() is $entityTypesWithoutRdfOutput, so I suspect this may be related to the fix for T213483.

It looks like this was an odd case of 3 servers not realizing that they had the latest config?

This only happened on 3 requests.

All requests are working fine now.

I also double checked the code and config and this should never happen in the first place.
