Loading problems with NPM Packages in Wix Velo

Question:
I am trying to use third party packages from NPM. Some like@tensorflow-models/universal-sentence-encoder package are getting downloaded but the whole code stops running when trying to import. I have made adjustments accordinging to the documentations but to no avail. Is there anything I can do to make it work?

What are you trying to achieve:
I want to use these libraries to run my custom code. While some libraries like fuzzball worked, others like word2vec, TensorFlow, natural are available, getting downloaded but not working. Why is that? How do I ensure they are imported and functioning properly.

What have you already tried:
There isn’t much on this; I tried finding other forum posts, etc. I have already gone through the document. All these libraries are supposed to function on the client side server as needed. There’s nothing otherwise needed missing. I have tried quite many variations of trying to structure my code.

You can run NPM-Packages on → BACKEND-ONLY <—

But it’s working for fuzzball, for eg.
