When upgrading the client from version 5.3.0 to 5.4.0, we ran into problems where the system projections were not picking up any events. After some digging, we noticed our Protobuf events were being interpreted as JSON.
Looks like the problem is caused by this line, which seems to ignore the current format of the event data and just forces it to JSON:

Should this take the current content type into consideration, or am I missing something?
