Use this chunk of code, this will tell you exactly on what column of which entity validation is failing, and you will eaisly reach the place where its creating problem.

 try
 {
     db.SaveChanges();
 }
 catch (DbEntityValidationException ex)
 {
     // Retrieve the error messages as a list of strings.
     var errorMessages = ex.EntityValidationErrors
                           .SelectMany(x => x.ValidationErrors)
                           .Select(x => x.ErrorMessage);

     // Join the list to a single string.
     var fullErrorMessage = string.Join("; ", errorMessages);

     // Combine the original exception message with the new one.
     var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);

    // Throw a new DbEntityValidationException with the improved exception message.
   throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
 }
