TypeError: h.ToneAudioBuffers is not a constructor

[floogy]

Fresh install (via PowerShell on Windows 10) results in the below upon visiting http://localhost:9876

JS Console displays a TypeError: h.ToneAudioBuffers is not a constructor, full message below:

UX lets me navigate past Keyboard selection then appears stuck on "Loading soundfont files..." with the Record button disabled.

Same problem, Linux Mint 20, Firefox browser, npm version 9.2.0

I installed via the instructions, npm install then npm start, then on opening browser window, I got the same result as floogy.

Looking for reasons, I scrolled back in the terminal output, and when I ran npm install npm said:

found 16 vulnerabilities (4 low, 4 moderate, 6 high, 2 critical)
  run `npm audit fix` to fix them, or `npm audit` for details

I then ran npm audit fix:

Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.

%c MusicVAE  background:magenta; color:white Initialized model in 0.00224s
Your app is listening on port 9876

Since I do not have a GPU, I ran npm i @tensorflow/tfjs-node, which completed successfully, though it still recommends installing it, so I presume the install did not get picked up.

After all that, I still get the same result.

I also tried on the Brave browser, with the same result but with a "Breaking Change" error:

Web MIDI will ask a permission to use even if the sysex is not specified in the MIDIOptions.

AFFECTED RESOURCES:

 - script.js:337

I wonder about the "critical" vulnerabilities (found 10 vulnerabilities (1 low, 4 moderate, 3 high, 2 critical)), but I am not sure what to do about them.

Not really a great JS dev, so I can't really offer any insight.

Thanks,

Squid

Just now seeing the hosted version, it doesn't hang like the local version, but it never actually creates the drum pattern either, just says Generating drums.... Looking in the console, I see the following (different!) error:

Uncaught Error: Cannot start playback while `Tone.Transport` is in use.

I don't really know if that is the issue, though.
