A frame hook threw on 3 frames in a row and the runtime removed it: recorded once, right after that third 'handler-threw', with `path` 'onFrame' and the function's `name`, when it has one, in `message`; never again for that hook. Its disposer then does nothing; call [`onFrame`](../api/Session.onFrame.md) again to run it.

## What to do

Fix the throw (see 'handler-threw') and call [`session.onFrame(callback)`](../api/Session.onFrame.md) again: the removed hook's disposer does nothing.

## Where the declaration names it

- [`Session.onFrame`](../api/Session.onFrame.md): A hook that throws on 3 frames in a row is removed ('handler-threw' each time, then 'hook-removed').

The set is open: handle a code you don't know (`'other'`).
