[BUG] PromptFlow does not start trace of flow

[JoeyRoeters]

Describe the bug
I've upgraded to PF 1.17.1. Previously when starting a flow it would automaticly start a trace for the running flow. Now when executing a flow
it doesn't trace it anymore.

How To Reproduce the bug

1. run flow with 'pf flow test --flow {flow}

Expected behavior
it should start the pf service and start a trace for the running flow. It used to log in the console the url to the trace, this does not happen anymore as well.

Screenshots

Running Information(please complete the following information):

• Operating System: MacOS 15.3 (24D60)
• Python Version using: 3.12.4

Additional context
The pf service is running, it did start the trace before the upgrade, after upgrading it's broken.
