fibonacci: script.js:8 Uncaught TypeError: app.generate is not a function

Marcus,

This is the closest example I can find to my little WASM exercise but I get this error:

main.wasm.js:9 wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'.
(anonymous) @ main.wasm.js:9
main.wasm.js:9 falling back to ArrayBuffer instantiation
(anonymous) @ main.wasm.js:9
script.js:8 Uncaught TypeError: app.generate is not a function
    at onSubmit (script.js:8)
    at HTMLFormElement.onsubmit ((index):14)
onSubmit @ script.js:8
onsubmit @ (index):14

What am I doing wrong?

Thanks,

Phil.
