Sequelize-Typescript无法初始化MySQL模型：类型错误求助

尝试使用Sequelize和Sequelize-Typescript将Node.js TypeScript项目连接到MySQL数据库时，无法初始化数据库模型，启动项目抛出如下错误：

TypeError: Cannot convert undefined or null to object
    at Function.getOwnPropertyDescriptor (<anonymous>)
    at /home/janneck/WebstormProjects/SchoolService/node_modules/sequelize-typescript/dist/model/column/column.js:18:131

模型定义代码：

import { Column, DataType, Model, Table } from "sequelize-typescript";

@Table({ tableName: "DocumentType" })
class DocumentType extends Model {
  @Column({ type: DataType.STRING, primaryKey: true })
  public documentTypeId: string;

  @Column(DataType.STRING)
  public name: string;
}
export default DocumentType;

项目原本包含多个模型，单独初始化该模型（无关联其他模型）仍失败。使用的依赖版本：

"sequelize": "^6.37.1",
    "sequelize-typescript": "^2.1.6"

• 检查TypeScript编译配置：确保tsconfig.json中开启experimentalDecorators: true和emitDecoratorMetadata: true，这两个是sequelize-typescript正常工作的必要配置。
• 清理编译产物后重新构建：删除项目中的dist目录，重新执行tsc编译，避免旧编译文件干扰。
• 调整版本兼容性：尝试升级sequelize-typescript到2.1.7，或降级sequelize到6.36.0，部分版本组合存在隐性兼容问题。
• 完善模型装饰器配置：给@Column的配置对象显式添加allowNull字段，比如@Column({ type: DataType.STRING, primaryKey: true, allowNull: false })，避免装饰器处理空值时出错。
• 确认模型加载路径：初始化Sequelize实例时，检查models配置的路径是否正确，确保模型文件被正确识别和加载。
