Capire Fiori Preview not working with latest Launchpad Version

[matteoprinetti]

To reproduce: Start Business Application Studio (or Visual Studio code) and create a new project:

cds init cap_test
cd cap_test
cds add samples 
npm install 
cds watch 

The usual Capire entry page will be shown but when I click on Fiori Preview

It used to work some releases ago but is broken now.

Thanks

Hi,

I can reproduce it with:

Using Business Application Studio with @sap/cds-dk@4.9.2 it works.

christian.georgi can you check it too?

Hi,

Is it possible that the problem is occurring again? We are currently experiencing the same issue, also rolling back to version 4.9.2 has no effect. Is there any additional configuration required to make it running on localhost?

Regards,
Jakob

It was a temporary issue. It works today w/o problems. Not sure what was the root cause though.

Hi Rene,

I tried today and still not working for me, maybe I have to upgrade cds-dk ? when clicking on "preview" I get now this in the browser

I'm not really convinced that an upgrade of cds-dk will solve it, but of course it doesn't harm 😉
Have you tried with a new project according to your description? That's what I did yesterday. I got rid of the one I created Friday and started from scratch.

Please try with clearing your browser cache once.

The CORS issue looks fishy to me, I don't get this.
Check by calling https://sapui5.hana.ondemand.com/resources/sap/ushell/ui/horizon/NewDesignSwitchItem.js in the browser, there should be a response header "access-control-allow-origin: * "

As of 13.05.2022 all is working again.

Hi
Seems like there is issue for all users trying to see Fiori Preview from localhost...
