So I tried to deploy this benchmark available here . I followed this steps:

1. Built the docker image
   docker build -t chamelon .

2. Tag the docker image
   docker tag chamelon imsuraj/chamelon:latest

3. Push the docker image to the repository
   docker push imsuraj/chamelon:latest

4. then tried to deploy the function (using openwhisk-deploy-kube deployment method)
   wsk -i action update chamelon --docker imsuraj/chameleon:latest --timeout 300000 --memory 256

5. then invoke the function
   wsk -i action invoke chamelon -r

And the rest is as follows

The problem is I couldn't find any logs which help me know what exactly is causing the issue. I also tried other benchmarks, same thing.
