Projection stream events with empty data attributes

I’ve discovered an event stream with empty data attributes.

It has two events: Result and $Eof
Their data attributes are empty at their metadata attributes are:

  "$ph": 1,
  "$cp": true

I’ve no idea how or why these were created. Our application has been running for over a year and nothing has been deployed in over a month.

Can anyone point me in the right direction?

Hi @Mike_Boehm,
The stream is the result of a query. The giveaway is the name of the projection which is GUID.

Thanks @pieter.germishuys
I consulted my colleague and that is in fact what happened.

many thanks
