Template fails to run after setup

[austincrim-pfg]

After running wrangler generate with this template and running npm run dev, the worker fails with a 500 status code.
Here's the error output:

"A hanging Promise was canceled. This happens when the worker runtime is waiting for a Promise from JavaScript to resolve, but has detected that the Promise cannot possibly ever resolve because all code and events related to the Promise\'s request context have already finished."

This regression was likely introduced by cloudflare/wrangler-legacy#1730, where the wasm binding was renamed to WASM_MODULE, we will need to change it here
