litmus: Network latency is not injected into my application

What happened: Executed Pod Network Latency Experiment, i do not see latency injected into the application

What you expected to happen: I have a very simple application deployed tom y K8S cluster. The demo application is based on this docker image

How to reproduce it (as minimally and precisely as possible): Created a basic deployment file that includes the above mentioned image. Created a service account based exactly as specified in this link. Chaos engine manifest also exactly looks like what was in the above mentioned link. I have replaced the app labels wherever appropriate. When I apply my chaos engine manifest, i can see that k8s creates a pod-network-latency pod as expected. When i look at the logs for the network latency pod, it is able to find the Application pod to inject latency into. Pumba pod appears to get created successfully. I have verified that the network interface of my application pod is eth0. The log files from network latency pod appear to be normal. Here is a sample from it

I have port-forwarded my application on port 8080. When I access the website localhost:8080, i expect to see network latency, but i don’t seem to see any. All XHR requests, that happens as part of the application are able to execute within 50 ms. Is this expected?

Anything else we need to know?:
