The bug

The Deploy a Resource Manager Template step breaks when you provide it an in-line ARM template which contains an object parameter.

What I expected to happen

The step should render the parameters then allow you to save the step.

Steps to reproduce

  1. Go to a project and add a new `Deploy a resource Manager Template'
  2. Navigate to the Template Source Section in the newly added step
  3. Choose the Source code option and click on the "Add Source" button.
  4. Enter the following template then click Save:
  "$schema": "",
  "contentVersion": "",
  "parameters": {
    "Kaboom": {
      "type": "object",
      "metadata": {
        "description": "The name of the web app that you wish to create."
      "defaultValue": {
        "count": 0,
        "intervalInSeconds": 0
  "resources": [ ],
  "outputs": { }
  1. Notice the error

Invariant Violation: Objects are not valid as a React child (found: object with keys {count, intervalInSeconds}). If you meant to render a collection of children, use an array instead.

Affected versions

Octopus Server: 2019.1.6-2019.2.3


Use a package instead of source code option for the ARM template or update the deployment process via the API. The latter will however result in the step breaking each time it's viewed.
