   Looks like this version is using vinxi. Can you upgrade to solid start 2.0 and see if it fixes it

   This error comes from @tauri-apps/api, not from SolidStart, and it does not depend on the SolidStart version.

   The screenshot shows getCurrentWebviewWindow() being called while Inner2 renders (app.tsx:5:25). It reads window.__TAURI_INTERNALS__.metadata, and window.__TAURI_INTERNALS__ is undefined. Only the Tauri runtime adds that object to the page. The page in the screenshot is open at localhost:3002 in a regular browser tab, not inside a Tauri window, so any Tauri window API throws there. SolidStart's dev overlay only displays the error. The same code throws on SolidStart 2.0, and in a plain Vite app.

   To make the app work in both places:

   • Check that you are running inside Tauri before calling Tauri APIs. isTauri() from @tauri-apps/api/core does this.
   • Call them on the client after the component mounts, for example in onMount or inside a clientOnly component. During server rendering there is no window at all.

   import { isTauri } from "@tauri-apps/api/core";
   import { getCurrentWebviewWindow } from "@tauri-apps/api/webviewWindow";
   import { onMount } from "solid-js";
   
   function Inner() {
     onMount(() => {
       if (!isTauri()) return;
       const win = getCurrentWebviewWindow();
       // use win
     });
     // ...
   }

   Closing, since this is not a SolidStart bug. If you see this error inside the Tauri window itself, please reopen with a small reproduction.
