One of the ways Webel IT Australia helps promote tools, technologies, and languages is by donating a lot of time identifying, tracking, and reporting potential issues, in order to help vendors and developers improve the tools and technologies. In some cases, we also offer workarounds and advice for users. All issues tracked on our public site are offered most constructively and with sincerest gratitude to the tool vendors and technology developers.
DISCLAIMER: Vendors do not officially endorse issue analysis by Webel IT Australia.

WORKAROUND: Add the Output block using the web version of Postman and it will then appear in the Desktop version when it syncs
