无法在简单迁移中读取未定义的属性“删除”

Question

I'm using the migrate-mongo library and have this simple migration to create a view. However I'm getting an error on migrate down.

ERROR: Could not migrate down 20220620114132-CreateContentView.js: Cannot read property 'drop' of undefined

module.exports = {
  async up(db, client) {
    db.createCollection('content', {
      viewOn: 'assets',
      pipeline: [...stuff]
    })
  },

  async down(db, client) {
    db.content.drop()
  }
}

I notice that this question has the same error: TypeError: Cannot read property 'drop' of undefined

However they're using mongoose where this isn't (shouldn't be)

Answer 1

I mixed up the mongodb terminal commands with node.js syntax. The drop line should be db.collection('content').drop()
