### Describe the bug

Could we get a working sample? the javascript examples don't export any logs, metric or traces. only the console shows entries for the javascript apps.

### Expected Behavior

_No response_

### Steps To Reproduce

### Anything else?

_No response_

Start by locating the JavaScript examples referenced in the issue and run them to confirm that logs, metrics, and traces appear only in the console. Done means a working JavaScript sample exports those signals through Aspire; the issue does not name specific files or tests.
