Json validation error in new version about java HOT 7 OPEN

Can you provide the body of the response that you got? You should be able to get it with ApiException.getResponseBody()

from java.

fwiw, I believe that this is either a bug in the openai spec or the kube api server.

If you look at the spec:

https://raw.githubusercontent.com/kubernetes/kubernetes/master/api/openapi-spec/swagger.json

If you search for ContainerImage you'll see that it is described as an array of string. In JSON null is not the same as []

I believe it needs to be either specified as a oneof(array, null) in that schema or the API server should never return null

from java.

Here is the part of the body that I think causes the error:

"images": [
    {
        "names": null,
        "sizeBytes": 974400966
    },
    ...
]

We are contacting a k0s server but the same call works with the legacy version of the client.

As a side note, the exception does not throw an ApiException, is it supposed to?

from java.

Thanks for the additional details. I would have thought that it would throw ApiException, but I guess there's no corresponding try/catch block.

With 20.0.0 we moved to a different code generator which is why there is a difference here.

For now, using legacy is probably the right thing to do. We need a reproduction in upstream k8s, not k0s to determine if this is really a bug.

from java.

I found the same error, which I can confirm is a bug, and the error message is as follows:
java.lang.IllegalArgumentException: Expected the field namesto be an array in the JSON string but gotnull`

at io.kubernetes.client.openapi.models.V1ContainerImage.validateJsonObject(V1ContainerImage.java:193)
at io.kubernetes.client.openapi.models.V1NodeStatus.validateJsonObject(V1NodeStatus.java:547)
at io.kubernetes.client.openapi.models.V1Node.validateJsonObject(V1Node.java:284)`

from java.

@pigstomach are you using k0s also? Or is this a true kubernetes api server?

from java.

Ok, I found the problem (I think):

OpenAPITools/openapi-generator#12549

We need to rev. past OpenAPITools/openapi-generator@7a7309e in the generator, likely update to 7.x (maybe 7.4?)

from java.
