Question

我是第一次（新手）使用Postman，测试了一个接受Json数据的Flask应用，而Postman一直给我这个错误yield call(action.meta.redirect, action.meta.path)，但我的Flask应用看来还可以。 Flask应用程序接受Json并返回There was an error in evaluating the test script: SyntaxError: Unexpected token ':'或200，但似乎工作正常……

这是我通过Postman控制台发送给Flask的Json： 400

有什么令人担心的吗？任何提示，不胜感激..

在Flask中，我可以将数据保存到sql似乎工作正常的{"Date": "2020-13-16T13:37:22.501743", "MeterReading": 5}响应。 200
