SqlException: The INSERT statement conflicted with the FOREIGN KEY

Guys, I have this error in ASP.NET 8 "Internal Exception 1: SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_RegistrationFormModels_SportModel_SportId". The conflict occurred in database "RegistrationFormDb", table "dbo.SportModel", column 'Id'." I am inserting the value 2 in this sport_id, but this value 2 exists in the bank. I don't know why it's giving this error

are you using C# with dapper or EF? the fk is correctly bonded with pk_sport_Id?

I'm using EF. I'm not sure, my model is like this

    public class RegistrationFormModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public DateTime DateTime { get; set; }
        public string GeneralInformations { get; set; }
        public int GenderId { get; set; }
        public string BirthCertificateImageUrl { get; set; }

        //Endereços
        public string CEP { get; set; }
        public string Street { get; set; }
        public string Number { get; set; }
        public string City { get; set; }
        public string State { get; set; }

        // Responsible Informations
        public string ResponsibleName { get; set; }
        public string PhoneNumber { get; set; }
        public string Email { get; set; }

        //Foreign Keys
        public int StudyShift_id { get; set; }
        public int Sport_id { get; set; }

        //Navigation Properties
        public GenderModel Gender { get; set; }
        public StudyShiftModel StudyShift { get; set; }
        public SportModel Sport { get; set; }

    }

    public class RegistrationFormModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public DateTime DateTime { get; set; }
        public string GeneralInformations { get; set; }
        public int GenderId { get; set; }
        public string BirthCertificateImageUrl { get; set; }

        //Endereços
        public string CEP { get; set; }
        public string Street { get; set; }
        public string Number { get; set; }
        public string City { get; set; }
        public string State { get; set; }

        // Responsible Informations
        public string ResponsibleName { get; set; }
        public string PhoneNumber { get; set; }
        public string Email { get; set; }

        //Foreign Keys
        public int StudyShift_id { get; set; }
        public int Sport_id { get; set; }

        //Navigation Properties
        public GenderModel Gender { get; set; }
        public StudyShiftModel StudyShift { get; set; }
        public SportModel Sport { get; set; }

    }

sport_id doesn't follow convention for what a foreign key should be named in EF, so this won't work unless you did some entity configuration that you have not shared
