Which error do you not understand? This seems like a normal game history for me. If you mean failing of interceptions, that can happen when you either intercept too late or do not choose a right card.

I mean, that player card wild draw four how to get 4 cards?

Ah sorry, the history was kinda hard to follow so I did not notice that it was your turn when he played that wild draw 4. That is indeed weird, never saw something like that in fact.

I'm sorry, I should have explained this first
