Jenkins Kubernetes plugin failing to provision jnlp-slave pods

I went to http://172.20.43.30:8080/configureSecurity/ and set "Agents:TCP port for JNLP agents" to "random"

I then got a "jnlp-slave-ttm5v (suspended)" that stays in the "Build Executor Status"

and the log said:

Container is waiting jnlp-slave-ttm5v [jnlp-slave]: ContainerStateWaiting(message=Error response from daemon: the working directory './.jenkins-agent' is invalid, it needs to be an absolute path, reason=CreateContainerError, additionalProperties={})

After setting "Working directory" to "/home/jenkins" I saw a pod actually get created on k8s:

# kubectl get pods --namespace=jenkins-slavesNAME               READY     STATUS    RESTARTS   AGEjnlp-slave-1ds27   2/2       Running   0          42s

and my job ran successfully!
