Companies House Streaming API - Blank JSON

I’ve noticed that a number of items returned from the Co House Streaming Service return with a blank JSON string.

Is this normal? There are thousands of records that get returned from the process but I need to know if I should handle these blank JSON strings being returned.

You may be receiving the “heartbeat” which is a blank new line that gets sent if there aren’t any events for a certain period, just to confirm that the connection is still alive.
