create a bundle:

duffle create foo

add definition and parameter section to duffle.json:

"definitions": {
    "manifest_file": {
      "default": "/cnab/app/kab/manifest.yaml",
      "type": "string"
    }
  },
  "parameters": {
    "fields": {
      "param1": {
        "definition": "manifest_file",
        "destination": {
          "env:": "MANIFEST_FILE"
        }
      }
    }
  }

build the bundle:

duffle build .

specifying the parameter results in the following error:

duffle install myfoo foo -s param1=/some/path.foo
Error: parameter param1 not defined in bundle

This is despite param1 being present in the bundle definition:

cat ~/.duffle/bundles/9460e8557e16656f0f35b991eeb376e1a4086283 | jq

    }
  },
