More info: I don't have the secondary event like "View" in my data, I just
don't collect the view event, since I'm using old purchased history of the
user.
With integration test data everything is Ok, but with my real data, it's
not. All the data looks like this with varying item_id and user_id. There
is no view events.
{"entityId":"00068116","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM8941"}
{"entityId":"00068116","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM8920"}
{"entityId":"00088894","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM66336"}
{"entityId":"00097710","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM42110"}
{"entityId":"00097710","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM61833"}
{"entityId":"00097710","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM65826"}
{"entityId":"00097710","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM40182"}
{"entityId":"00097710","entityType":"user","event":"purchase","targetEntityType":"item","targetEntityId":"BM5001"}
Is my data wrong? I am able to successfully train and deploy the engine.
