Mock server 'Something went wrong' error

I’ve been getting intermittent errors on creating mock servers with the postman app. Some additional details:

  • macOS mojave 10.14.5
  • postman app Version 7.1.0 (7.1.0)

It worked the first time i tried this tutorial, but then following the same steps again gives this error.

I’ve tried:

  • Clearing out all old mock, requests, responses et al
  • Upgrading to latest postman app (Version 7.1.0 (7.1.0))

I had the same trouble, but I tried to set up the server mock from the button “New” on the top left side and works without problems. Before I tried to do it from the 3 dots of the collection and not work.
I hope can help you.
