The "streamName" stream managed by projection "3" has been written to from the outside

I publish event this name of stream $ce-nameOfStream
But this error appears when i console by_category projection in eventstore UI.

Can Someone explain what this error mean? and how to fix it?

Thanks

From what I understand , you appended an event to to $ce-nameOfStream ?
Any event or stream beginning with “$” are system managed streams and should not be appended to by applications.
you’ll have to reset that projection .

thanks for your response,

I update my code and publish events with streamName without $ce like this

  • streamName-{id}

I acces to eventstore UI, I reset the projection ‘by_category’ but nothing happen, the problem is the same
