Given an invalid hour, it returns internal-server-error. I was expecting a bad request.

$ curl --location --request PUT 'http://localhost:3000/api/trainer/calendar/make-hour-available' \
--header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX3V1aWQiOiIxIiwiZW1haWwiOiJ0cmFpbmVyQHRocmVlZG90cy50ZWNoIiwicm9sZSI6InRyYWluZXIiLCJuYW1lIjoiVHJhaW5lciIsImlhdCI6MTYzMDkyNDE3NH0.veziMkcul16lUnQwV7HnNPSf19AkntaDlPDRfNYBkKI' \
--header 'Content-Type: application/json' \
--data-raw '{
    "hours": [
        "aaaaaa"
    ]
}'
