Hel loo all! This is my function

public async create({ request, response }: HttpContextContract) {
    // find or create team
    let team: typeof Team
    let r = request.body
    if (r.existingTeamId) {
      team = await Team.findOrFail(r.existingTeamId)
    } else {
      team = await Team.create({
        title: r.title,
        size: r.size,
      })
    }
    // create teammembers
    r.teamMembers.forEach(
      async (member) =>
        await TeamMember.create({
          ...member,
          name,
          position,
          email,
          teamId: team.id,
        })
    )
    // create training
    const training = await Training.create({ title: r.title, body: r.training.body })

    // create teamLead
    const teamLead = Team.create({ teamlead_first_name: r.firstName, teamlead_last_name: r.lastName, teamlead_email: r.email, teamlead_id: r.teamLeadId })


    return response.json(training)
  }

So if there will be team id i will find that team if there will not be team id then user must create new team then in create team members user must add multi members and there i will get team.id so then user must create training and then team lead thats in teams table so whats i'm doing wrong here? i'm new in this so this is very hard for me so can someone please help me?
