Lerp does not work with timeline

Ok thanks for the help everyone. i tried to do like you suggested, i just added two more parameters to Move to Point, now it has:
Start Location, Start Rotation, End Location, End Rotation (i think it’s better use transforms at this point) and now the interp works! doing another test, i found that i can also use those Get nodes but instead using Alpha value from the timeline i could use Get World Delta Seconds and the result is almost the same, maybe smoother.
Just another issue that i don’t get how to solve:
Every time i play the game, and then i stop it, UE warns me a couple of same errors:
Blueprint Runtime Error: “Accessed None trying to read property ActualCamera”.
ActualCamera is a reference of my Camera inside the level, i take it from my GameMode on its BeginPlay with GetAllActorsOfClass and save the first (and the only one) value in a variable.
It seems like in a certain point of the Runtime the program does not found the level camera. Tell me what i had to screen. Thanks.
