On SAP Web IDE Multi-Cloud version, when right clicking and going to Run > Run as > Web Application or SAP Fiori Launchpad Sandbox it gets to the SAML authentication and that stops on a white screen, with no errors in the console log.
I've tried this on custom apps I've created and also a new SAPUI5 app from template, nothing works. It only works if I deploy it to the SAP Cloud Platform then register it to my personal Fiori Launchpad.
I've tried the exact same in the standard SAP Web IDE version (non- Multi-Cloud version) and it works.
If anyone knows the solution to this, it would be great.
Thanks
