Unable to use shopping cart in v9.0 (ApiServer) Web Portal

Dear community

We updated our OneIM development environment to version 9.0.
Since the update, it is not anymore possible to use the "add to shopping cart" button in the (ApiServer) web portal.
A click on the button does not have any visible effect and does not generate an immediate error.

The only thing that catched our eyes on the client side is the following JavaScript error logged in the browsers developer console when loading the web portal.
Uncaught ReferenceError: require is not defined
at scripts.6ade27e10c0168f9.js:1:49961


We tried it with latest versions of Microsoft Edge (Chromium based), Firefox and Google Chrome and saw the same result in every browser.

We already created a service request (#01860130) for this issue but it doesn't seem to have reached the responsible team yet.

Is anybody else seeing the same issue with 9.0?
Maybe   can comment?

Best regards,
Manuel
