The Node 20.19 integration job on #23573 failed with expected undefined to deeply equal { inAppVar: 'in app value' } in adds local variables to out of app frames when includeOutOfAppFrames is true. That PR does not touch LocalVariables, and the same suite passed on Node 22, 24, and 26 in the same run.

Root cause: LocalVariables captures vars on a worker that attaches after inspector.open(). The out-of-app scenarios threw after a fixed 500ms, which is short enough on a loaded runner for the throw to land before pause-on-exceptions is enabled — so the event is sent without vars. Other tests in this suite already wait 1000ms; these two did not.

Decision: wait until inspector.url() is actually set, then give the worker a beat to enable the debugger, instead of lengthening another blind timeout. Frame lookup also accepts Object.<name>, which this suite already treats as a valid Node function-name variant.

Unrelated to #23573.

These scenarios threw after a fixed 500ms, which can beat the debugger worker on loaded CI and drop vars from the event.

Closing: this is not currently failing on develop. Node 20.19 integration tests passed on the latest develop runs (including https://github.com/getsentry/sentry-javascript/actions/runs/32880176511 and the fully green https://github.com/getsentry/sentry-javascript/actions/runs/32874078613). The failure was a one-off flake on #23573, not an ongoing develop breakage.
