ValueError when using list_event_for_all_namespaces #1826

Closed joaompinto closed 7 months ago

joaompinto commented 2 years ago

What happened (please include outputs or screenshots):

Attempting to use client.EventsV1beta1Api().list_event_for_all_namespaces() results in an Exception ... File "C:\Users\lameg\miniforge3\lib\site-packages\kubernetes\client\models\v1beta1_event.py", line 290, in event_time raise ValueError("Invalid value for event_time, must not be None") ValueError: Invalid value for event_time, must not be None

What you expected to happen: Get a list of events

How to reproduce it (as minimally and precisely as possible): Run the following code snippet targeting a minikube cluster:

from kubernetes import config, client

config.load_kube_config()
api = client.EventsV1beta1Api()
print(api.list_event_for_all_namespaces())

Anything else we need to know?: A workaround was provided at https://stackoverflow.com/a/72591958/401041 .

Environment:

larsks commented 2 years ago

To add some information to this issue, the behavior in the description is being triggered by events like this, in which eventTime is null:

{
  "apiVersion": "v1",
  "count": 33623,
  "eventTime": null,
  "firstTimestamp": "2022-05-28T19:48:56Z",
  "involvedObject": {
    "apiVersion": "cdi.kubevirt.io/v1beta1",
    "kind": "CDI",
    "name": "cdi-kubevirt-hyperconverged",
    "resourceVersion": "563035442",
    "uid": "d2d2434c-c1f6-4f27-98cb-1a69106dd9c1"
  },
  "kind": "Event",
  "lastTimestamp": "2022-06-13T16:54:23Z",
  "message": "Successfully ensured SecurityContextConstraint exists",
  "metadata": {
    "creationTimestamp": "2022-05-28T19:48:56Z",
    "name": "cdi-kubevirt-hyperconverged.16f35ca1771fe01e",
    "namespace": "default",
    "resourceVersion": "604296130",
    "uid": "3b21aeb3-2100-4559-8c2f-2064f5af831d"
  },
  "reason": "CreateResourceSuccess",
  "reportingComponent": "",
  "reportingInstance": "",
  "source": {
    "component": "operator-controller"
  },
  "type": "Normal"
}

I'm not affiliated with @joaompinto, but I see around 1000 events that have null eventTime on our cluster, so presumably this isn't uncommon.

This is a genuine bug, it's just got me. Looking for alternatives now. I need to list events, but not watch them which is what the watcher script does.

I'm hitting this bug after creating an event with EventsV1Event. The only way I was able to create the event was with a utc timezone, as suggested in https://github.com/kubernetes-client/python/issues/730:

events_api.create_namespaced_event(
                namespace=namespace,
                body=EventsV1Event(
                    kind="Event",
                    type="Normal",
                    event_time=datetime.now(timezone.utc),
                    ...

However that datetime does not seem to be correctly seralized and stored even with the workaround. When I query the events I get this traceback:
