Changelog Entry

Description

Fixes #22748 — The InputVariablesModal component throws ReferenceError: idx is not defined at line 39, causing the prompt variables modal to show an infinite loading spinner. The entire prompt variable feature is broken.

Root cause: The {@const} destructuring with rest syntax ({ type, ...variableAttributes }) inside an {#each} block triggers a scoping issue in Svelte 5's legacy compatibility mode, where the loop index variable idx becomes undefined in the compiled output.

Fixed

  • Renamed loop index from idx to variableIdx to avoid the naming collision
  • Replaced {@const} rest destructuring with Object.fromEntries(Object.entries(...).filter(...)) to work around the Svelte 5 compilation scoping bug

Screenshots or Videos

Before: Modal shows infinite loading spinner, console shows ReferenceError: idx is not defined
After: Modal renders correctly, prompt variables can be filled in
