Can not execute argo workflow due to Invalid 'when' expression in workflow file

Question

Error:-

I'm getting the error of Invalid 'when' expression '{{steps.check-channel-exists.outputs.result}}': Invalid token: '{{'.

I'm trying to execute the workflow here. Can someone point me in the right direction so that I can solve this?

Answer 1

solved it:) Looks like Argo can't get POD output. My workaround is to grant roles:

kubectl create rolebinding default-admin --clusterrole=admin --serviceaccount=argo:default
