Basically the first program with these stupid open issues. You can download a better written program from indian malware sites. Shame

The app did not open, however no error was thrown.
This is my first time using Postman, and I could very well be misusing the application.
However, I expect that opening an app… should open the app.

Here are the logs from the main.log file,

This is only a minor inconvenience because I will be using the website builder (until I am forced to revisit this issue due to browser limitations).
If I do find a resolution I will be sure to post here.

Hey @_Octal :wave:

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).
