How to create windows correctly？

[Xiaobaishushu25]

i use this code to create window:

import {WebviewWindow} from "@tauri-apps/api/webviewWindow"
 const webview = new WebviewWindow('setting', {
    url: '/#/setting',
    center: true,
    width: 1025,
    height: 800,
    minWidth: 1025,
    minHeight: 625,
    decorations: false,
    resizable: true,
    dragDropEnabled: false,
  });
  await webview.show()

The window was created as expected and runs smoothly,,but the console always shows a 'window not found' error. Is the process of creating the window incorrect for me? How to eliminate this error?

this is the info:

Assuming the error really stems from just that code i assume it's the webview.show() line because it may be called before the window was fully created (hence the tauri://created event you may have seen in the docs).
Do you even need that line? If you don't spawn the window with visibile: false this shouldn't do anything anyway. If you do need it, try moving it into the tauri://created event handler.

I also got the same 'window not found' error.
Adding:

"core:window:allow-show",
"core:webview:allow-create-webview-window",

to my capabilities json permissions fixed it for me.
