How to deal with 400 error messages

Work with an application made in xamarin that sends several requests to the api. Eventually, a user action gets a BAD REQUEST because the user tried to enjoy a photo that she had previously enjoyed, or try to follow another user she was already following and for some reason the app did not show that she was already enjoying / following. And that mistake just came as a crash. My question is whether I should give a catch on this error and delete, or log in as the same error. For the user does not change anything, the experience of the app remains the same, no error, no crash.
