Description

Suppose you have something like:

  template:
    from:
      uri: "google-storage://{{bucketNameOrArn}}"
      parameters:
        autoCreateBucket: "{{autoCreateBucket}}"
        serviceAccountKey: "base64:{{serviceAccountKey}}"
        deleteAfterRead: "{{deleteAfterRead}}"

and you want to have serviceAccountKey as optional parameter. If you prefix the parameter with '?', like

  template:
    from:
      uri: "google-storage://{{bucketNameOrArn}}"
      parameters:
        autoCreateBucket: "{{autoCreateBucket}}"
        serviceAccountKey: "base64:{{?serviceAccountKey}}"
        deleteAfterRead: "{{deleteAfterRead}}"

We'll try to encode the value anyway, even if not specified.
