插入关系表多对多时出错

Question

我正在尝试使用 typeORM 和 Nestjs 将关系数据保留在 mysql 数据库中，但它在数据库中明显显示错误

Entity:

  @ManyToMany(()=> Stock, stock => stock.seals)
  @JoinTable()
  stock: Stock[];

Service:

var c = getConnection().getRepository(Seals).save(createSealDto)
     return c 

Error:

错误 [ExceptionsHandler] 无法添加或更新子行：外键约束失败 (stocksystem.stock_seals_seals, CONSTRAINT FK_70140d58e95fbceed988b224e64 FOREIGN KEY (stockId) 参考 stock (id) ON DELETE CASCADE ON UPDATE CASCADE)

负载：

{"client":{"id":1},"stock":[{"id":1},{"id":1}],"price":398}
