The main problem is that when we reject Promises, Node10 and Node16 behaviour is different.
For Node 10, when a promise was rejected without a .catch block will be emitted only unhandledRejection
For Node 16, when a promise was rejected without a .catch block will be emitted unhandledRejection first (if exists), and uncaughtException at the end.
In azure-pipelines-task-lib we handle all uncaughtExceptions and set TaskResult.Failed.
So when we use node16 runner, it emits uncaughtExceptions on Promise rejection and the task fails, and when we use node 10 it does not emit uncaughtExceptions so the task successfully finishes.
The event "unhandledRejection" was added on process.on to emit uncaughtExceptions on node10
