Dinner sample fails to export data to the collector

[NicFontana]

Hi,

I am trying out the Dinner sample following this guide in the documentation, but when I run the executable I got this failure logged in the terminal:

Is there anything I should check out to confirm everything is properly set up?

I am running it on

• macOS Sonoma 14.3.1
• Swift 5.9
• Xcode 15.2

Thank you.
