Happens on latest amberframework/granite version

Example table:

items

CREATE TABLE items
(
  id         INT AUTO_INCREMENT   PRIMARY KEY,
  type_id    INT            NOT NULL
  price      DECIMAL(10, 2) NULL,
  type_name  VARCHAR(255)   NULL,
  published  TINYINT(1)     NULL,
  created_at TIMESTAMP      NULL,
  updated_at TIMESTAMP      NULL,
)

item.cr

require "granite_orm/adapter/mysql"
  class Item < Granite::ORM::Base
    adapter mysql
    table_name items
    field type_id : Int32
    field type_name : String
    field price : Float64
    field published : Bool
    timestamps
  end

app.cr

Item.create(type_id: 99, published: true, type_name: "Anshar", price: 99.00)
p Item.find 1
