Mistral looses the return value of a JavaScript action if it returns a JSON or an array

[Michal Gershenzon]

Workflow that reproduces the problem:

---
version: '2.0'

test_js_json:
  output:
    result: <% $.javascript_task %>

  tasks:
    javascript_task:
      action: std.javascript
      input:
        context: <% $ %>
        script: |
          return { "key": "value" };
