I cloned the following in BTP for Fiori exercises: https://github.com/SAP-samples/sapui5-development-learning-journey.git

When I want to preview the app (no matter which branch I choose) I get the following error: "Error while starting preview. Details: AggregateError"

This is a known issue with Fiori Tools extension for BAS, SAP has a fix for it due to be released Feb 9.

Please see my last response in this thread.+

Before then, you need to stop and restart your Dev Space to work around the issue.

How to restart the Dev Space? Does restarting the Dev Space work with the BTP Trial?

EDIT: sorry, got it:

NB: I could solve by restarting the BAS in a new InPrivate window.

Hi,

Try to install below command then you can able to preview the application.

 "npm i @SAP/ui5-builder-webide-extension"

Thanks & regards,

Prashanth.

the correct package name is in lowecase:

 

npm i @ sap/ui5-builder-webide-extension

 

(remove the space after "@", this is an issue of this forum)
