output from previous action cannot be used

[ffoysal]

a sample porter.yaml is

outputs:
- name: kubeconfig
  description: "Kubeconfig for the newly created "
  type: string
  applyTo:
  - install
  - upgrade
  - uninstall
install:
  - exec:
      description: "Display Cluster info"
      command: bash
      flags:
        c: cat /root/.kube/config
      outputs:
      - name: kubeconfig
        path: /root/.kube/config
uninstall:
  - exec:
      description: "Uninstalling: get kubeconfig from outputs"
      command: bash
      flags:
        c: "echo {{ bundle.outputs.kubeconfig }} > /root/.kube/config" 

after install I can see the output using porter instances output show kubeconfig -i hack
when I do porter uninstall hack got this

uninstalling hack...
executing uninstall action from Test (bundle instance: hack)
Error: unable to resolve sourced values: unable to resolve step: unable to render template exec:
  command: bash
  description: 'Uninstalling: get kubeconfig from outputs'
  flags:
    c: "echo {{ bundle.outputs.kubeconfig }} > /root/.kube/config"
: Missing variable "kubeconfig"
Error: failed to uninstall the bundle: container exit code: 1, message: <nil>. fetching outputs failed: error copying outputs from container: Error: No such container:path: 2f4ab208d54d3d9fc6d96e70faf62c73c43e3c0413da180f2c584400a0b18095:/cnab/app/outputs

any idea ??

Thank you for the issue @ffoysal ; indeed Porter should support output value interpolation between actions. I'll dig in.
