 const result = await Post.findOne({ _id: postId }).populate('comments')
 if (!result) {
 return NextResponse.json({}, { status: 400 })
 }
 return NextResponse.json({ data: result })
}

findOne까지는 문제없는데 populate('comments') 에서 에러남 구글링해도 문제가 뭔질 모르겠네 gpt는 딴얘기만하고 살려주삼


Schema hasn't been r.egistered for model "Comment"
