Hey @_Octal 
Those logs indicate it’s from the Postman Agent, it’s a helper app to enable sending of requests using the Postman web app - Once you have the web-app open, select the “Desktop Agent” to send the request using the Postman Agent (Make sure it’s running).
More details here: Announcing Postman for the Web, Now in Open Beta
Alternatively, download the Postman native app from here: Download Postman | Get Started for Free 
Cheers
