Current behavior

My project has no errors, i'm getting data from postman but when i try to post something, i'm getting an error. Seems like typeorm is adding "_rid" to my relations

Expected behavior

Just Post endpoint

Minimal reproduction of the problem with instructions

async createStudent(
  createStudentDto: CreateStudentDto,
  user: User,
): Promise<any> {
  const foundUser = await User.findOne(user.id);
  foundUser.details = createStudentDto.details;
  foundUser.sports = createStudentDto.sports;
  foundUser.level = createStudentDto.level;
  foundUser.calendar = createStudentDto.calendar;
  foundUser.save();
}

query failed: SELECT User_targets_rid.target_id AS "target_id", User_targets_rid.student_id AS "student_id" FROM "targets" "targets" INNER JOIN "student_targets" "User_targets_rid" ON (User_targets_rid.student_id = $1 AND User_targets_rid.target_id = "targets"."id") ORDER BY User_targets_rid.target_id ASC, User_targets_rid.student_id ASC -- PARAMETERS: [108]

What is the motivation / use case for changing the behavior?

is not working
