当我尝试从 API 获得的 JSON 中打印数据时，出现此错误。它确实打印正确，但控制台上出现此错误，我不确定如何修复它。

HTML

{{datas[0].dimension}}

TS

datas: Data[];
this.abcService.getDatas().subscribe(datas => {
  this.datas = datas;
  console.log(datas);
});

从 API 获取的 JSON（console.log）

(1) [{…}]
0:
  dimension:"bla bla bla"
__proto__:Object
length:1

控制台上的完整错误
