uncaught error when running locally

[tseelbach]

When testing assert failures locally in vsCode, the monitoring scripts as written per the examples will fail with something like:

Uncaught Object Proxy(Error)
at throwUnhandledRejectionsMode (<node_internals>/internal/process/promises:391:5)
at processPromiseRejections (<node_internals>/internal/process/promises:470:17)
at processTicksAndRejections (<node_internals>/internal/process/task_queues:96:32)
promises:391
Process exited with code 1

This is because the assert failure causes an unhandled exception locally.
In Instana sythetic monitoring there is a handler for this so we get the expected result from the assert like this example:

AssertionError [ERR_ASSERTION]: Expected a 200 status code, statusCode is 200
at ReadOnlyHandler.apply (vm/bridge.js:468:15)
at /tmp/96VHwN2S5idFET8uFR54_bb32189c-1985-4271-a3f6-0ac560879410/script.js:38:10
at process.processTicksAndRejections (node:internal/process/task_queues:105:5)

To fix this locally I added this to the bottom of my async function:

})() //.catch(error => {
//console.error('Local execution error:', error.message);
//});
// Failed asserts will throw an exception.
// For local execution, uncomment the above 3 lines to catch and print the error.
// In Instana Synthetic Monitoring, errors are handled by the platform

There is an example of this in examples/got-get.js but it's not documented.
It would be helpful if you added this code to some of the examples, and a paragraph in the README.
Thanks!
