Retrofit 2 - Response body null when response status is 422 (unprocessable entity)

Question

I\'m using Retrofit to make a POST Request in my web server.

However, I can\'t seem to get the response body when the response status is 422 (unprocessable entit

By default, when your server is returning an error code response.body() is always null. What you are looking for is response.errorBody(). A common approach would be something like this:

    @Override
    public void onResponse(Response response, Retrofit retrofit) {
        if (response.isSuccess()) {
            response.body(); // do something with this
        } else {
            response.errorBody(); // do something with that
        }
    }

If you need something advanced take a look at Interceptors and how to use them
