When preparing a workshop for SAP Partners this week I ran into a problem that an app that I created using SAP Web IDE full stack did not Show up in preview mode.
I only got a blank screen.
I was able to run the app after having it deployed to SAP CP and after having it registered in the Fiori Launchpad of my trial account.
The error that hit me was that the Destination webide_di which is required for SAP Web IDE full stack to run and which is normally automatically created when activating the Service in your Trial account was missing for whatever reason.
This destination is documented here but it is not shown how to create it manually.

If you also encounter this problem and if it turns out that the destination webide_di is missing in your trial account as well you can copy the following Content into a text file, replace the string 'd0#####trial' with the name of your trial account (marked in bold letters in the following URL)
https://webidecp-d0#####trial.dispatcher.hanatrial.ondemand.com/
and import it in the SAP Cloud platform cockpit.
