What happened?

When I set this in my config:

    BackgroundGeolocation.ready({
      ...
      activity: {
        triggerActivities: ["in_vehicle"],
      },
      ...
    })

I get this error in the logs:

2026-05-19 21:48:21.925 ⚠️-[TSConfigModuleBase setValue:forProperty:] TSActivityConfig: Could not set 'triggerActivities': -[__NSSingleObjectArrayI length]: unrecognized selector sent to instance 0x142801fd0

What I'm attempting to do is restrict what movement will reset the stop-timeout counter. It resets constantly and will never let the app go back to stationary mode.
