Sequelize adds id(PK) of main table in findAll with 'group' and currupts a query with it in posgre.

Hello! I have Products model, and Vendors model. With assocation that Vendor has many products and product has one vendorId. I need filter vendors by product properties and/or vendor properties. Using postgre 9.6 and camelcase columns. Sequelize 3.30.2

Therefore object for querying:

 Products.findAll({
      attributes: [],
      where: { type: 'service' },
      include: [{model: Vendors, attributes: ['id', 'name', 'description'], as: 'vendor', required: true, where: { approved: true } }],
      group: ['vendor.id']
    })

Generates incorrect query (with “Products”.“id”):

SELECT “Products”.“id”, “vendor”.“id” AS “vendor.id”, “vendor”.“name” AS “vendor.name”, “vendor”.“description” AS “vendor.description” FROM “Products” AS “Products” INNER JOIN “Vendors” AS “vendor” ON “Products”.“vendorId” = “vendor”.“id” AND “vendor”.“approved” = true WHERE “Products”.“type” = ‘service’ GROUP BY “vendor”.“id”;

Query without “Products”.“id” works fine and returns vendorId`s filtered by vendor parameters (or/and product parameters):

SELECT “vendor”.“id” AS “vendor.id”, “vendor”.“name” AS “vendor.name”, “vendor”.“description” AS “vendor.description” FROM “Products” AS “Products” INNER JOIN “Vendors” AS “vendor” ON “Products”.“vendorId” = “vendor”.“id” AND “vendor”.“approved” = true WHERE “Products”.“type” = ‘service’ GROUP BY “vendor”.“id”;

Is any way to tell Sequelize to not include primary key if I don`t want it in attributes?

Thanks!

Adding raw: true to the main object solves this issue.
