 - [Issue #548](https://github.com/tywalch/electrodb/issues/548); Fixed invalid `ProjectionExpression` generated for entities without a sort key when using the `attributes` option. An empty string was incorrectly added to `ExpressionAttributeNames`, causing DynamoDB to reject the request.

-- Fast follow to 3.6.0, relaxes projection attribute constraint on collection entities. 3.6.0 required [collection] member entities to all share the same attributes when using a `projection` defined index. This constraint came from the original scope of 3.6.0. Thankfully, due to the work of [@anatolzak](https://github.com/anatolzak), 3.6.0 shipped with robust collection typing and this no longer was a concern.
