I was using the previous DXA version where it was possible to use empty regions
<tri:entities region="HeaderRegion"/>
Doing a migration to 1.4, we just changed the tag to:
<dxa:entities region="HeaderRegion"/>
But we realised that this is not working anymore. When we try to render the page we've got the error
Region not found on page: GeneralHeader
How can we have the same behaviour as before?
