我花了一天的大部分时间试图解决这个极其烦人的错误。

我正在使用 redux-toolkit、MSW、RTK 查询和 React 测试库，目前正忙于编写一个测试简单登录流程的集成测试。

我遇到的问题是我正在一个测试套件中测试两种不同的场景，一种是成功登录，一种是失败登录。

当我一次运行一个时，我没有遇到任何问题，但是当我同时运行两个时，我会收到以下失败场景的错误。

TypeError: Cannot convert undefined or null to object

      60 |         const { payload } = action;
    > 61 |         adapter.upsertMany(state, payload);
         |                 ^
      62 |       }
      63 |     );
      64 |   },
