TypeORM迁移PostgreSQL时触发栈溢出错误求助

执行TypeORM迁移时出现栈溢出错误，原项目中遇到该问题后，新建空白项目仍可复现。

配置文件（ormconfig.ts） #

import { DataSource } from 'typeorm';

const env = {
  "DB_HOST":"localhost",
  "DB_PORT":5432,
  "DB_USERNAME":"postgres",
  "DB_PASSWORD":"postgres",
  "DB_DATABASE":"task-management",
}

export const connectionSource = new DataSource({
  migrationsTableName: 'migrations',
  type: 'postgres',
  host: env.DB_HOST,
  port: env.DB_PORT,
  username: env.DB_USERNAME,
  password: env.DB_PASSWORD,
  database: env.DB_DATABASE,
  logging: false,
  synchronize: false,
  name: 'default',
  migrations: ['migrations/**/*{.ts,.js}'],
});

执行的迁移命令 #

typeorm-ts-node-esm migration:run -d migrations/ormconfig.ts

初始错误信息 #

Error during migration run:
    RangeError: Maximum call stack size exceeded

排查过程 #

推测是DirectoryExportedClassesLoader.ts存在循环依赖导致无限循环，于是在该文件第26行添加console.log(JSON.stringify(exported))，得到新错误：

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'DataSource'
    |     property 'driver' -> object with constructor 'PostgresDriver'
    --- property 'connection' closes the circle
    at JSON.stringify (<anonymous>)
    at loadFileClasses (/Users/christianayscue/Desktop/nestjsClass/typeormTest/src/util/DirectoryExportedClassesLoader.ts:29:25)

可见当存在循环依赖时，DirectoryExportedClassesLoader.ts会因递归调用触发栈溢出错误，恳请协助解决！
