Hey, thanks for the report. This is a known issue, Glass omnibar automatically adds https:// to file:/// URLs. A partial fix was done earlier, but omnibar specifically wasn’t updated.

As a workaround, you can run a local server for preview:

  • python -m http.server from the folder with the file
  • npx serve

Then open it via localhost in the built-in browser.

I’ll let you know if there are any updates.
