What part(s) of Essentia.js is involved?

• essentia.js-core (vanilla algorithms)
• essentia.js-model (machine learning algorithms)
• essentia.js-plot (plotting utility module)
• essentia.js-extractor (typical algorithm combinations utility)

Description

I'm trying to use essentia models to predict genre / mood of a song to improve my recommendation system using node js , i've followed some tutorials of essentia on github but i'm facing two problems well explained below

Steps to reproduce / Code snippets / Screenshots

-1ST PROBLEM ⛔

• I've imported EssentiaWASM like this
  

• PS : i've tried to import it like this like some tutorials but it makes an error :
  
  error :
  

-Now when i'm using the first import to instantiate the extractor for using with "musicnn" models :

• I'm facing this error :
  

-2ND PROBLEM ⛔

• I've used a musicnn model ( https://essentia.upf.edu/models/autotagging/msd/msd-musicnn-1.json )
• Then i've to tried to used like this but the line 53 cause me a problem :
  
• The Error :
  
  Exactly here :
  

Please i need a solution for both problems to extract the features correctly with the exractor and for the tenserflow Js problem while loading the model
