Why do the camera and the character not move when I use my own mapping context?

I replaced the defult mannequin with my character and created a new input action and an input mapping context.

But when I change the default mapping context to mine, the camera and the character never move, and I can’t move the character using the buttons, nor can the camera move like before when I move my mouse.
