Answer 1

You probably have filter typed as object[] as well. And property project does not exist on object. If you don't care about typing, you can declare filter as Array<any>:

let filter: Array<any>;

Answer 2

这样做，问题就消失了，

private filter: any[];

Answer 3

The problem may be with your flow.service.ts field where you have set that to type object and all the field in filter don't exist on the type object . In your flow.service.ts change the feild type to any.

filter: any;

Answer 4

使用名称过滤器初始化对象，例如：

filter = [];
