Error while starting preview. Details: AggregateError

[willem_bakkes2]

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"

Were you talking about this tutorial: https://learning.sap.com/learning-journeys/develop-sapui5-applications/getting-started-with-sapui5-d... ?

Hi,

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

 "npm i @Pa_Vi/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)
