Responsebody of BadRequest (and other errors)

[Baklap4]

when trying to get the users and do supply a wrong api-version in the header it always just returns Bad Request and not showing the response body..

The json of the response body should've been:

{
    "code":400,
    "message":"BadRequest: The HTTP resource that matches the request URI 'http://localhost:30002/users' does not support the API version '1.3'.",
    "meta":{
        "apiVersion":[
            "1.3"
        ]
    }
}

When i'm running the request with Curl it does give me the desired output.

When reporting an issue, please provide the following details:

Obviously we can't test that because we don't have the server you're running with.
Try opening the developer tools in your browsers and check the network tab when you try it out.
What's the actual response you see in the console?

[Baklap4]

Of course you can test it easily

Step 1

Create a GET route for anything you like

Step 2

Define a reponse model like i did

Step 3

Define a model which the api will return

Step 4

Check with a valid request

Step 5

Check with a not valid request < Which triggers a bad request

Step 6

Match Step 5 with the curl request generated by swagger-ui

Output of curl in my example:

{
    "code":400,
    "message":"BadRequest: The HTTP resource that matches the request URI 'http://localhost:30002/users' does not support the API version '1.3'.",
    "meta":{
        "apiVersion":[
            "1.3"
        ]
    }
}

Output in swagger-ui
Bad Request << nothing more nothing less

Expected the schema i've defined in my yaml to be filled in and shown to the user of swagger-ui

Same issue：
3.x：

2.x：

I want it shows the response body no matter what status code it is, otherwise I have to read the response body in Chrome Web Developer Tools：

[clery]

Same thing here

It does the same thing wether the error is documented or not, but its ok with success codes (200-299)

Closing as duplicate of #3041.

[Baklap4]

I love the fact that #3041 is created later and this is marked as duplicate hahah 😂 The first explains it better though + providing a sample 👍

[webron]

It's true - however the majority of the discussion is there. I could have been technically right and closed the other in favor of this one, but preferred going with where the main focus is.
