App function extension not compiling to wasm. Possible bug?

I'm trying to set up a javascript app extension/function using the discount tutorial here: 

https://shopify.dev/docs/apps/selling-strategies/discounts/experience/getting-started

And I'm unable to get past step #1 part 8 to deploy the app (npm run deploy). Specifically, I'm getting an error that says:

 

The following function extensions haven't compiled the wasm in the expected path:

product-discount: extensions/product-discount/dist/function.wasm 

Make sure the build command outputs the wasm in the expected directory. 

It's clearly looking for a wasm file, but when I run the build command (npm run build) it outputs a javascript file in the dist folder instead of a wasm file. extensions/product-discount/dist/function.js. Is this a bug or is there something missing from the tutorial? Should I be building in a different way than the included node command? There is no mention of building in the tutorial.

 

Details:

I used the npm init @Shopify/app@latest command from this tutorial to build a node app.

https://shopify.dev/docs/apps/getting-started/create

The app was successfully installed on my dev store and otherwise works fine.

 

Node version 14.19.0

NPM version 9.6.6

Shopify CLI version 3.45.4

 

Any help would be appreciated. Thanks.

This is an accepted solution.

I upgraded to Node 20.1.0 and it compiled correctly. The docs say the minimum required Node version is 14.17.0. That should be updated.
