ChaosToolkit --var-file option is fails with error Error: no such option: --var-file /tmp/token.env

Question

We are trying to run a chaos experiment and running into this error:

ubuntu@ip-x-x-x-x:~$ kubectl logs -f  pod/chaos-testing-hn8c5 -n <ns>

Here is the spec file:

We have also tried using the --var "KEY=VALUE" which also failed with the same error. Any help with this is appreciated. We have hit the wall at this point in time

Docker image being used is: https://hub.docker.com/r/chaostoolkit/chaostoolkit/tags

The kubernetes manifest is slight incorrect. The environment variable injection worked when passing it like this:

args:
        - --verbose
        - run
        - --var-file
        - /tmp/token.env
        - /experiment/terminate-all-pods.yaml

The option flag and its value needed to be on two separate lines
