Describe the bug

How to Reproduce

git checkout main

pnpm test

  270 passing (960ms)
  5 failing

  1) ProblemService
       deleteProblem
         should return deleted problem:
     TypeError: Cannot read properties of undefined (reading 'deleteMany')
      at ProblemService.deleteProblem (apps/admin/src/problem/problem.service.ts:517:31)
      at async Context.<anonymous> (apps/admin/src/problem/problem.service.spec.ts:265:22)

  2) GroupService
       getGroups
         should return a list of groups that showOnList is true:

      AssertionError: expected { …(2) } to deeply equal { …(2) }
      + expected - actual

             "id": 4

  4) SubmissionService
       getContestSubmisssions
         should throw exception if user is not registered to contest:

      AssertionError: expected promise to be rejected with 'NotFoundException' but it was rejected with 'TypeError: Cannot read properties of …'
      + expected - actual

      -TypeError: Cannot read properties of undefined (reading 'findFirst')
      +NotFoundException

  5) SubmissionService
       getContestSubmisssions
         should throw exception if contest doesn't have this problem:

      AssertionError: expected promise to be rejected with 'NotFoundException' but it was rejected with 'TypeError: Cannot read properties of …'
      + expected - actual

      -TypeError: Cannot read properties of undefined (reading 'findFirst')
      +NotFoundException

 ELIFECYCLE  Test failed. See above for more details.

와 같이 현재 local에서 mocha test를 돌리면, 에러가 나오는데, GitHub CI에서 잡히지 않습니다. 빨리 해결해야 될 문제로 보입니다.
