SAP BAS - SAPUI5 visual editor does not open with 403 code

[VictorHo]

Hello SAP team,

I created an adaptation project to extend a standard SAPUI5 app from an on-premise system.

I want to use SAPUI5 visual editor to extend the app. However, the tool does not open. I got this error notification: "Request failed with status code 403"

Look like I'm missing some authorization? But what is that? I couldn't find the documentation on this error.

So I'm looking forward to your support.

Thanks a lot.

Vuong.

Hi hoq1hc ,

My assumption is that the number of ports in BAS were exhausted.

Go to 'View' => 'Find Command' then select 'Ports: Preview'. If there are 5 ports listed you should unexpose at least 1 to be available for the SAPUI5 Visual Editor, because there is a limit to the count of the ports that can be exposed in the same time. To unexpose a port: Go to 'View' => 'Find Command' then select 'Ports: Unexpose' and click on one of the listed ports to unexpose it. Do not unexpose "Theia hosted instance".

Then refresh the browser tab and try again with the SAPUI Visual Editor.

Thanks a lot raz.korn,

I solved the issue.

Hopefully, SAP can improve in the next version of SAP BAS with a clear error message on the reason, so that we have clue on how to fix the issue.

Thanks again,

Vuong.
