sequelize select and include another table alias

I'm using sequelize to acess a postgres database and I want to query for a city and for example include the "Building" table but I want to rename the output to "buildings" and return the http response but I have this error:

{ SequelizeEagerLoadingError: building is associated to city using an alias. You'v e included an alias (buildings), but it does not match the alias defined in your a ssociation.

    City.findById(req.params.id,{
      include: [
        {
          model: Building, as: "buildings"
        }
      ]
    }).then(city =>{
      console.log(city.id);
         res.status(201).send(city);
    }) .catch(error => {
     console.log(error);
     res.status(400).send(error)
   });

city Model

            const models = require('../models2');
            module.exports = (sequelize, DataTypes) => {
              const City = sequelize.define('city', {
              name: { type: DataTypes.STRING, allowNull: false },
                status: { type: DataTypes.INTEGER, allowNull: false },
                latitude: { type: DataTypes.BIGINT, allowNull: false },
                longitude: { type: DataTypes.BIGINT, allowNull: false },

              }, { freezeTableName: true});
              City.associate = function(models) {
                // associations can be defined here
                 City.hasMany(models.building,{as: 'building', foreignKey: 'cityId'})
              };
              return City;
            };

As you have defined alias name in below code is building :

City.hasMany(models.building,{as: 'building', foreignKey: 'cityId'})

But in query , you are using buildings

include: [
  {
     model: Building, as: "buildings" // <---- HERE
  }
]

It should be building :

include: [
   {
         model: Building, as: "building" // <---- HERE
   }
]
