ApiException cause or message is blank #2066

Closed MissakaI closed 6 months ago

Describe the bug I am trying to create a statefulset using AppsV1Api and it throws a ApiException with no cause to identify what the issue is.

Compete Stacktrace as follows:

        appsApi.createNamespacedStatefulSet("default",statefulSet,null,null,null);

        return ContainerCreateResponse.builder().id(id).build();
    }

Expected behavior Either create the statefulset or throw an exception with proper message

KubeConfig If applicable, add a KubeConfig file with secrets redacted.

Server (please complete the following information):

Additional context Tried it with a incorrect attempt to create a pod using CoreV1Api which resulted in an exception with no cause as well. And with a correct config it creates the pod with no issues at all. So that proves the kubernetes api is reachable and has proper access priviledges.

brendandburns commented 2 years ago

I don't think that this is a bug in the client. If you look at the place where the exception was thrown:

https://github.com/kubernetes-client/java/blob/master/kubernetes/src/main/java/io/kubernetes/client/openapi/ApiClient.java#L973

It is setting response.message() to be the message for the exception. For some reason the server that you are talking to is returning an empty status line in it's HTTP response. I think you will need to debug your server for more information.

You can try printing APIException.getCode() or APIException.getResponseBody() to get more details from the exception that may help with this debugging.

Thanks for the tip on ability to print the response body using APIException.getResponseBody(). So this is one of output I got when i printed the response body.

{"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"StatefulSet.apps \"selenium-standalone-firefox04699455\" is invalid: [spec.selector: Required value, spec.template.metadata.labels: Invalid value: map[string]string(nil): `selector` does not match template `labels`]","reason":"Invalid","details":{"name":"selenium-standalone-firefox04699455","group":"apps","kind":"StatefulSet","causes":[{"reason":"FieldValueRequired","message":"Required value","field":"spec.selector"},{"reason":"FieldValueInvalid","message":"Invalid value: map[string]string(nil): `selector` does not match template `labels`","field":"spec.template.metadata.labels"}]},"code":422}

In the response the message field is present. But still the ApiException stacktrace doesn't print the message.

brendandburns commented 2 years ago

fwiw, the message field in the Status response is unrelated to the message that is passed to the exception.

The message passed to the ApiException is an okhttp.Response.message so I still suspect that this is because the HTTP status message coming back from the server is empty.

If you look at the ApiException code there's no way that the response body can get set w/o also passing in a message to the exception.

Can you try printing ApiException.getMessage() explicitly and see what it prints?

MissakaI commented 2 years ago

As you suggested ApiException.getMessage() function worked. It printed the returned message field in the previously attached response body.

abelsromero commented 2 years ago

We are struggling with similar scenario but we cannot call methods since errors occur during startup via Spring configuration for example. We end up with simple io.kubernetes.client.openapi.ApiException: with no info, for example could be for lack of permissions for the service account or API not available in some cloud provider/k8s version, but it's not possible to know. Would it make sense (even if under some config flag) to add the response body to the message so it's shown by default.

stevenschlansker commented 2 years ago

We are running into this problem as well - ApiException is thrown with a null message, and the inherited Exception.toString method does not know about the responseBody, so it does not get printed and all you see is ApiException: null which is extremely unhelpful.

abelsromero commented 2 years ago

I run into the same thing today, and resorted to making a custom build of the client adding this to ApiException (btw, kudos for how easy it was, mvn package and done!).

  @Override
  public String getMessage() {
    String code = String.valueOf(getCode());
    return code + getResponseBody();
  }

With that I went from

I am not argueing this is trivial and should be done based on code lines count, we should probably sanitize the output and account for many more things. But I hope this exemplifies the struggles of not having any information when an error happens and you are not the one calling the API directly. Now I know I forgot to correctly setup the service account 🤦

Maybe we can start a conversation on a approach?

nodejh commented 2 years ago

I run into the same issue too.

I can't get some important information about the problem, because the ApiException#message is null when an exception occurs during leader election.

I create a CustomLeaderElector class which copy from io.kubernetes.client.extended.leaderelection.LeaderElector and overwrite tryAcquireOrRenew() method to print more message of ApiException, finally, I find my problem from the ResponseBody.

public class CustomLeaderElector {
  // ...
  private boolean tryAcquireOrRenew() {
        // ...
        try {
            oldLeaderElectionRecord = lock.get();
        } catch (ApiException var6) {

           // print more message of ApiException
            log.error("tryAcquireOrRenew ApiException, code: {}, message: {}, header: {}, response: {}", var6.getCode(), var6.getMessage(), var6.getResponseHeaders(), var6.getResponseBody());

            if (var6.getCode() != 404) {
                log.error("Error retrieving resource lock {}", lock.describe(), var6);
                return false;
            }
    }
}

Log:

[2022-06-16 17:56:05.464] [ERROR] [leader-elector-lease-worker-1] com.aliyun.actiontrail.client.CustomLeaderElector tryAcquireOrRenew:233 - tryAcquireOrRenew ApiException, code: 403, message: , header: {audit-id=[3316d6ae-1619-4676-8132-ecbbbacb0579], cache-control=[no-cache, private], content-length=[427], content-type=[application/json], date=[Thu, 16 Jun 2022 09:56:05 GMT], x-content-type-options=[nosniff], x-kubernetes-pf-flowschema-uid=[6373319d-163d-483f-98c5-e8b80c0cd018], x-kubernetes-pf-prioritylevel-uid=[8aadd4ee-cb09-40c3-9b4b-814d2b7d4b38]}, response: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"leases.coordination.k8s.io \"xxx\" is forbidden: User \"system:serviceaccount:xx-service:default\" cannot get resource \"leases\" in API group \"coordination.k8s.io\" in the namespace \"xx-service\"","reason":"Forbidden","details":{"name":"xxx,"group":"coordination.k8s.io","kind":"leases"},"code":403}

The ApiException#message is null and the ApiException#responseBody#message is not null, but we can't get responseBody in stack trace. So I think it would be better to add correct error message in ApiException#message.

aespinosa commented 2 years ago

fwiw, the message field in the Status response is unrelated to the message that is passed to the exception.

For some reason the Response#message() being passed is proably null? It's supposed to be an string interpretation of the HTTP Status code based on https://square.github.io/okhttp/4.x/okhttp/okhttp3/-response/. Maybe we can inspect the response object prior to the ApiException being code inside a debugger and isolate it into an OkHttp bug?

aespinosa commented 2 years ago

in practice, i liked setting ApiClient#setDebugging(true) to workaround the lack of verbosity in ApiException when trying to reproduce issues.

Turns out, if there is no change, the issue doesn't just magically solve itself, no matter what the bot wants.

oops...

fwiw, I did actually notice that there is a constructor where the response body can be set without the message getting set:

https://github.com/kubernetes-client/java/blob/master/kubernetes/src/main/java/io/kubernetes/client/openapi/ApiException.java#L58

We may need an upstream fix in the client generator to fix this.

We are still affected by this. What will it take to get some attention here? Serviceability is very important for having Kubernetes be a usable platform. I would be happy to file a PR, but it looked like the above fix was too surface level to be the right fix, and it is not likely that a community member will be able to step up and push through a fix to a code generator...
