Can't pass comma separated values to --set in arkade install

Expected Behaviour

arkade install openfaas \
  --set queueWorker.image=alexellis2/pro-queue-worker-demo:0.1.1 \
  --set httpRetryCodes=429,502,500,504,408

Current Behaviour

The following error appears:

VALUES values.yaml
Command: /home/alex/.arkade/bin/helm [upgrade --install openfaas openfaas/openfaas --namespace openfaas --values /tmp/charts/openfaas/values.yaml --set gateway.directFunctions=false --set queueWorker.image=alexellis2/pro-queue-worker-demo:0.1.1 --set ingressOperator.create=false --set httpRetryCodes=429,502,500,504,408 --set basicAuthPlugin.replicas=1 --set queueWorker.replicas=1 --set queueWorker.maxInflight=1 --set basic_auth=true --set serviceType=NodePort --set clusterRole=false --set operator.create=false --set openfaasImagePullPolicy=IfNotPresent --set faasnetes.imagePullPolicy=Always --set gateway.replicas=1]
Error: failed parsing --set data: key "502" has no value (cannot end with ,)
Error: exit code 1, stderr: Error: failed parsing --set data: key "502" has no value (cannot end with ,)

Possible Solution

Possibly the argument needs to be quoted?

Helm does support arrays and maps being passed as strings, however this is not one - it's just a string that's comma separated.

Steps to Reproduce (for bugs)

As per above

Context

This particular setting cannot be overridden with --set, and it may affect other charts also.
