When i opened this link with 1.132.1 it worked:
https://ui5.sap.com/1.132.1/test-resources/sap/fe/core/fpmExplorer/index.html#/buildingBlocks/rte/rteDefault

It also worked with 1.133.0:
https://ui5.sap.com/1.133.0/test-resources/sap/fe/core/fpmExplorer/index.html#/buildingBlocks/rte/rteDefault

Then i tried again without version and it worked again 🤔
It also worked in incognito mode in chrome.

Strange error, maybe it is something with cache, may have a look if you can improve something.

attached is console.log and network trace

Hello @marianfoo,

I am not able to reproduce this issue. Can you give us more information on the browser you have used to reproduce it. Can you confirm that you still get the same error when initially loading the page?

Kind regards,
Nikoleta

All good, it was the double slash in the initial link that caused the error
