Linter crashes on Mac due to absent stdout on result of WorkerJob. #68053
Description
This occurred on a Mac host while trying to reproduce a linter error on the bot.
The stack trace in the linter was:
NoSuchMethodError: The getter 'isEmpty' was called on null.
Receiver: null
Tried calling: isEmpty
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5)
#1 main (file:////engine/src/flutter/ci/bin/lint.dart:248:28)
<asynchronous suspension>
#2 _startIsolate.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:299:32)
#3 _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:168:12)
The line that caused the exception reads if (job.result?.stdout.isEmpty ?? true) which indicates that the ProcessRunnerResult.stdout was null. Unclear why this can be the case.
