DeleteNamespacedDeployment : com.google.gson.JsonSyntaxException: java.lang.IllegalStateException:

[sandeepsingh3]

Hi,

I am trying to delete a deployment using ExtensionsV1beta1Api. Sample code below
try{
ExtensionsV1beta1Api apiInstance = new ExtensionsV1beta1Api();
String name = valMetaData; // String | name of the Deployment
V1DeleteOptions body = new V1DeleteOptions(); // V1DeleteOptions |
String pretty = "true"; // String | If 'true', then the output is pretty printed.
Integer gracePeriodSeconds = 56; // Integer | The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
Boolean orphanDependents = false; // Boolean | Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
String propagationPolicy = "Foreground"; // String | Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
try {
apiInstance.deleteNamespacedDeployment(name, nameSpace, body, null, null, null, null);
System.out.println("delete deployment");
} catch (ApiException e) {
System.err.println("Exception when calling ExtensionsV1beta1Api#deleteNamespacedDeployment");
e.printStackTrace();
}

	}catch(Exception e){
		e.printStackTrace();
	}

However i am getting the below exception

Any idea what is the issue

This is a duplicate of #86

That issue has the details, basically Kubernetes can return either Status or Object when deleting something and the Swagger/Java client can't handle multi-type return...

Closing as duplicate.
