That exception is being thrown here, which doesn't really show what the root cause is:

cactbot/resources/overlay_plugin_api.ts

Lines 91 to 102 in 5f18714

	const processEvent = <T extends EventType>(msg: Parameters<EventMap[T]>[0]): void => {
	init();
	const subs = subscribers[msg.type];
	subs?.forEach((sub) => {
	try {
	sub(msg);
	} catch (e) {
	console.error(e);
	}
	});
	};

Can you open dev tools, breakpoint there, and then re-trigger the error by reloading the overlay, then get a full stack trace from the exception?

I got this in the dev tool console :

oopsy_live.bundle.js:3652
TypeError: Cannot convert undefined or null to object
    at run (oopsyraidsy_data.bundle.js:224)
    at ValueOrFunction (oopsy_live.bundle.js:22119)

    at processEvent (oopsy_live.bundle.js:3648)

Does it helps ?

[valarnin]

It is failing the delete in the General Well Fed trigger, either because data.lostFood is null/undefined or matches.target is null/undefined, neither of which should be possible in a default setup.

    {
      id: 'General Well Fed',
      type: 'GainsEffect',
      netRegex: NetRegexes.gainsEffect({ effectId: '30' }),
      run: (data, matches) => {
        delete data.lostFood[matches.target];
      },
    },

Do you have custom user js modifying anything?

[mooondark]

No, there's only the example files in the user folder (and I'm not a dev, so there will never be anything in this folder 😉).

I tried on 2 differents machines, same error.
