Not able to forward logs via fluentdforwarder

[Shalu22111]

I am using Openshift Cluster version 4.8, while deploying the LogForwarding yaml file, it is throwing an error stating: no matches for kind "LogForwarding" in version "logging.openshift.io/v1alpha1". Due to which it is not creating the Fluentdforwader instance and logs are not being transferred to Splunk.
While deploying Splunk statefulset yaml file, it is throwing error: create Pod openshift-logforwarding-splunk-0 in StatefulSet openshift-logforwarding-splunk failed error: Pod "openshift-logforwarding-splunk-0" is invalid: spec.volumes[1].name: Duplicate value: "openshift-logforwarding-splunk".

Please help me to resolve this issue as I am not able to create fluentdforwarder and splunk statefulset resources.

How are you deploying the resources? If you are using Helm, it should install log-forwarding-instance.yaml not log-forwarding-instance-tp.yaml.
It looks like it is trying to install on an OpenShift Platform lower than 4.3.
