Error: Cannot invoke method tokenize() on null object

@bravenel I've run in to an issue in Rule Machine 3.0 running

I was creating this new Triggered Rule:

I was in the "Select Actions for True" window and had just added the switches per mode action. I was clicking through the "Select Action Type to set" dropdown list trying to find which action type to select to be able to run a RM action when I got this error message:


It threw me back to the "Define a Triggered Rule" window with the first action saved. Every time I try to go in to the "Select Actions for True" now I get the same error message.

The logs do not add much to the error message:

I get a similar error when trying to go in to "Select Actions for False": java.lang.NullPointerException: Cannot invoke method tokenize() on null object (selectActionsFalse)

I have created a new rule with the same settings but I was unable to reproduce the error there. I've still got the failing rule if you want to have a look at it

I'll look into it. Thanks.

Can you show me the app status for the broken rule? Gear icon.

Did you edit those actions before or after adding the Switch per mode? Was there some other action there that was deleted? Like maybe a Custom Action?

I was creating the Triggered rule as it's displayed in the screenshot above, from top to bottom in one go. I had just added the first action for true (the switches per mode) and went on to add a second action. I was clicking through the action type dropdowns to see what options there were in the actions dropdown for each type when it threw me out, but I didn't add another action

OK, thanks for the clarification.

I've managed to reproduce it once now. I'm currently documenting every step I'm doing trying to reproduce it again

While I was able to reproduce it once, I don't remember exactly what I did to trigger the issue. I have tried over 90 different combinations now, while documenting it, but haven't been able to reproduce.

The steps I know I did when I was able to reproduce it were:

  1. Create new Rule
  2. Set the conditions and define rule
  3. Convert to triggered rule
  4. Set the trigger event
  5. Set the switches per mode as actions for true (don't click "Done with actions for true")
  6. Select an action type from the dropdown list
  7. Select an action from the dropdown list, without adding this action
  8. Repeat 6-7 with different action types and actions until it errors

I'm pretty sure I was somewhere in the bottom 4 action types ("Set Private Boolean, Run/Stop", "Run Custom Action or Custom command", "Delay or Repeat Actions" or "Conditional Actions") when the issue last occurred, but I was unable to reproduce that later.

ah ha, so there was more going on. The thing is, the application state you showed revealed that Custom Action had been selected. And, I found a problem with selecting Custom Action but not completing it. That is most likely what threw the error, although I'm not able to get it happen either. A fix for this has been done, and will be in the next release.

Sorry about the wild goose chase but it did lead to a bug being found at least. Hopefully it was also that bug that caused my issue. Thank you!

Same error here. Did this get released?

You need to show the error, and the rule that caused it.

Goodbye! RuleBuilt In App

Do you see the Broken Action in your rule? That's the cause. You need to fix that. That came from some improper input while setting up the action. You have to delete that action, and put in whatever action belongs there. You could start by trying to Edit Action for that, and that might give you a clue for what it was supposed to be.

Exactly, but when I click into the Action sections, Hubitat throws error so I can't delete the broken action. There is no way for me to get inside the rule to remove the broken action.

Then you will have to delete the rule and re-create it.

It would be nice to make this error proof, meaning to at least be able to delete the broken action and make a small adjustment vs recreating the rule altogether.
