Hello everyone, I am a novice who is familiar with Three.js. I installed the three dependency using the command npm install – save three in the Vue framework, and then copied the code from the tutorial webgl_rorphtargets_face.htmlhttps://threejs.org/examples/?q=face#webgl_morphtargets_face to index.html and made modifications. After running the project with the command npx vite, no faces appeared on the webpage. Then use F12 to check if the error is: I want to ask if this is the cause.
Here is my code:

After adding the following code on the basis of the above code, I was able to display 3D faces again, but adding additional code did not meet my expectations:
<script type="importmap">

}
