Kube API Server - Issue with job retrieval after creation

Hi,

I am working with creating K8s job via K8s API client for some use cases. Job creation is successful but sometimes API server returns null when job is being fetched.
Does server queues the request to create job and immediately return the response and there can be delay between actual creation of job and responding to create job request ?
In what cases api server returns null when job is being fetched by client ?
