Cannot bundle snarkjs correctly.

[abcfy2]

Hi there. I have snarkjs in my source code, but building using ncc seems not working.

Here is my sample project:

tmp.tar.gz

You can use:

npm ci
npm start

to reproduce my issue.

async function plonkVerify() {
  const {proof: _proof, publicSignals: _publicSignals} =
    await wrappedSnark.plonk.fullProve(
      {c: 18, a: 3, b: 15},
      path.join(circuitsRoot, 'adder.wasm'),
      path.join(circuitsRoot, 'adder.zkey')
    );
  console.log('finish code');
}

plonkVerify();

Bundle snarkjs by ncc will never execute code console.log('finish code');. Output:

❯ npm start

> start
> ncc run src/index.ts -e snark.js

But when I set "start": "ncc run src/index.ts -e snarkjs", and run again. It works very well. Output:

❯ npm start

> start
> ncc run src/index.ts -e snarkjs
