Rest Client Error when getting body content when an error

[Alex Soto Bueno]

Hi, I'm developing a very simple Rest Client API that makes a call to an external service. This external service might return a HTTP 500 error code but with body content.

If I execute the call using curl I got the following thing:

curl bubble-backend:8080/bubble -v

*   Trying 172.30.5.96:8080...
* TCP_NODELAY set
* Connected to bubble-backend (172.30.5.96) port 8080 (#0)
> GET /bubble HTTP/1.1
> Host: bubble-backend:8080
> User-Agent: curl/7.67.0
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 500 Internal Server Error
< content-type: application/json
< content-length: 80
< x-envoy-upstream-service-time: 4
< date: Thu, 09 Dec 2021 12:56:15 GMT
< server: envoy
<
* Connection #0 to host bubble-backend left intact
{"color":"yellow","hostname":"bubblebackend-v1-dd5bf5754-wx854","requests":1539}

So as you can see the external service is returning correctly the 500 server error and with body content.

Then in Rest Client, I have the following code (the code is a bit redundant but I am trying different things):

try {

JsonObject bubble = bubbleService.bubble();

statistics.add(bubble);

return bubble;

} catch(WebApplicationException e) {

System.out.println(e.getResponse().readEntity(JsonObject.class));

JsonObject bubble = (JsonObject) e.getResponse().getEntity();

statistics.add(bubble);

return bubble;

}

The exception is thrown correctly but when I try to read the entity I got:

Caused by: java.lang.IllegalStateException: RESTEASY003291: Input stream was empty, there is no entity
        at org.jboss.resteasy.specimpl.BuiltResponse.readFrom(BuiltResponse.java:147)
        ... 32 more

In theory, there should be a body content but the exception that is thrown is that it is empty.

Any idea?
