我想我已经找到了解决方案.这个 API 在 browser 和 Postman 上也能正常工作.但是如果你注意到 PostMan，状态是 402
根据
我不确定 Heroku 为何发送 402 请求，但根据 ljk 的回答，您的帐户似乎未完全激活.
你可以进一步读出Retrofit Class Response,
<块引用>如果 code() 在 [200..300] 范围内，则返回 true.
Help me out. I am using retrofit for my project and I am totally new on it. I am getting the following error. Why I am getting a false response?

Help me out what should I do to solve this issue?
I think I have found a solution. This API is working perfectly fine over browser and Postman too. But if you notice on PostMan, the status is 402
As per MDN Web Docs
The HTTP 402 Payment Required is a nonstandard client error status response code that is reserved for future use.
Since, retrofit follows status code 200 as success, the response body in your case is null.
However, if you closely look at the debug console, the value (json) is present, but in the errorBody.
I am not sure why Heroku is sending 402 request, but as per ljk's answer, it seems your account is not fully activated.
You can further readout Retrofit Class Response,
Returns true if code() is in the range [200..300).
