Issue using externalPackages Not Excluding Dependencies

I am trying to use fabric fabric/node in a convex node action and it seems it's dependency canvas cannot be bundled and will produce this issue when deploying convex functions

 No loader is configured for ".node" files: node_modules/fabric/node_modules/canvas/build/Release/canvas.node

    node_modules/fabric/node_modules/canvas/lib/bindings.js:3:25:
      3 │ const bindings = require('../build/Release/canvas.node')


It seems to me that the solution should be to add this to convex.json as shown here https://docs.convex.dev/functions/bundling#external-packages

{
  "node": {
    "externalPackages": ["canvas"]
  }
}


However this does not solve the issue

Also I think that adding node.externalPackages does nothing as I did an experiment

{
  "node": {
    "externalPackages": ["lodash"]
  }
}


But when I npx convex dev --once --debug-bundle-path /tmp/myBundle I still see lodash being bundled. I would have expected myBundle to contain a 
node_modules
 folder with lodash there separately (if I have understood this correctly).


Sample Code


I created a minimal reconstruction branched from one of the convex-samples, and put my node action in convex/issue.ts
Steps to reproduce
Checkout repo
npx convex dev --once --debug-bundle-path /tmp/myBundle


You can see my failed debugging attempt to externalize lodash here https://github.com/ziggy6792/convex-issue/tree/debug/bundle-lodash

And my failed attempt to externalize canvas here https://github.com/ziggy6792/convex-issue.git


Any help would be greatly appreciated or if someone has a sample repo where node.externalPackages is demonstrated that would be great (maybe I do not understand how it should work)

Thanks!
