Null pointer exception on config update

[Dagon-]

I'm testing out 1.1.31 which was working very well until I hit the following exception trying to update a config

Process:

• Push two templates to nifi 1.4.0
• Pull config
• Add a connection to config.json:

"connections": [
    {
      "name": "test_connection",
      "source": "root > SimulateDataMinrAlerts",
      "destination": "root > Publish_to_Kafka "
    }
  ],

• Run update config:

I see there was a previous issue #26, am I misreading that this should have been fixed or is this something different?

Hello,
it's not the same problem as # 36.
Do you have multiple controllers with the same name in one of the templates?

Do you have multiple controllers with the same name in one of the templates?

I don't believe so, but I'm new to nifi and I didn't create these templates (my goal being to investigate getting some automation around nifi).
You can see the templates here: https://pastebin.com/U0EJQp3b and here: https://pastebin.com/V6GK9ZJv if you want to check them out yourself.
