Fiori Tools: error loading webview

[htammen]

I've installed Fiori Tools in my local VS Code installation.
When I run "Fiori: Open Application Generator" from the Command Palette I get this error:

Error loading webview: Error: Could not register service workers: 
InvalidStateError: Failed to register a ServiceWorker: 
The document is in an invalid state..

Installed Fiori Tools
version: v1.5.2
Last updated: 2022-03-17

Any suggestions?

Thanks Helmut

Hi Helmut,

Thanks for the extensive information. It's a strange one, and it looks like the Application Wizard is not installed successfully in your VSCode environment. The application wizard is a VSCode extension from SAP that should be a wrapper for any Yeoman generators that are installed locally (including the Fiori generator). For some reason, there's an error on startup with it.

Can I suggest that you uninstall the Application Wizard and re-install it? In the extensions view in VSCode you should be able to uninstall it, and then search for it again in the Marketplace to re-install it. I'll also ask the development team for the Application Wizard to comment here to see if they can support you.

Thanks

Ian

Things become strange now.

As you suggested I deinstalled the application wizard.
When I, after a restart of VS Code, go to the marketplace and click any Extension I get this strange error. I havn't even clicked the "install" button, just clicked on the extension in the list view.

I guess my environment is the problem but I have no idea where to start the search.

Thanks so far
Helmut
