Azure Static Web App with SolidStart?

[GS-Ray]

Has anyone tried to develop an Azure Static Web App (ASWA) using SolidStart?

Out of the box, ASWA supports a number of popular frameworks, such as React, Angular, Vue, Svelte, but not SolidStart. I tried to use the Custom framework option. However, ASWA, in the process of building, is looking for an index.html file:

...
Try to validate location at: '/bin/staticsites/de49310b-2af8-48a1-8710-f2a4fcd3e0c4-swa-oryx/app/.output'.
Finished building app with Oryx
Failed to find a default file in the app artifacts folder (.output). Valid default files: index.html,Index.html.
If your application contains purely static content, please verify that the variable 'app_location' in your workflow file points to the root of your application.
If your application requires build steps, please validate that a default file exists in the build output directory.
...

Looks like the SolidStart equivalent is .output/server/index.mjs?

Would really like to use SolidStart with ASWA. Any help would be appreciated.

BTW, I come from a Java, HTML, CSS, JS, Apache Wicket background. So I'm fairly new to this stuff. Apologies for any dumb questions.
