We are receiving the following error form our projection:
The stream managed by projection has been written to from the outside.
We initially create a stream from outside the Projection (we have tried it via the .NET driver and Postman) then start out projection which us filtered to a specific Category and Event Type.
After an event is received, we try the following:
emit(dailyStream, “TillTransactionStartedEvent”, new TillTransactionStartedEvent(e), new MetaData());
It’s at this stage we get this error.
We have tried various combinations of parameters in emit in case we had made a mistake, but we keep getting the same error message.
