Exception when updating config map using kubernates client

Question

UseCase : When updating configmap with new entries along with existing entries.

Issue : We are seeing below exception and I am not able to reproduce below issue frequently.

I went through decompiled version but couldn't find cause of this issue . Could some one help on when this issue can happen. How can we resolve this ?

Code used to update ConfigMap :

KubernetesClient client = new DefaultKubernetesClient(new ConfigBuilder().build()); final ConfigMapBuilder configMapBuilder = new ConfigMapBuilder().withNewMetadata() .withName(deploy_config).endMetadata(); configMapBuilder.addToData(status, status.name()); client.configMaps().withName(deploy_config).createOrReplace(configMapBuilder.build());

Exception:

io.fabric8.kubernetes.client.KubernetesClientException: An error has occurred.
