Can this work in AWS lambda functions?

I can't seem to get the simple example to work in AWS lambda function. Appears to error on the upash.install line. Here is my function...

const upash = require('upash');
upash.install('argon2', require('@phc/argon2'));

exports.handler = function (event, context, callback) {
    try {
        console.log('===> body: ', event.body);
        const hp = event.body.split('&');
        const handle = hp[1].split('=')[1];
        const pass = hp[0].split('=')[1];
        console.log('===> handle: ', handle);
        console.log('===> pass: ', pass);
        (async () => {
            const hashstr = await upash.hash(pass);
            callback(null, {
                statusCode: 200,
                body: JSON.stringify({ hashstr })
            });
        })();
    } catch (error) {
        callback(null, {
            statusCode: 500,
            body: JSON.stringify(error)
        });
    }
};

If you move the upash.install inside the handler, the code will run up until it hits the upash.install line then the function errors (with a blank error message) at that point. So this is some kind of hard/can't-handle crash on that line when running in lambda functions

With the upash.installl line above/outside the function (like the code shows) you get a 'path' error...

I've looked through the install function and cant see a reason that it wouldnt work in a serverless environment. I can't seem to see the reference to upash in the stack trace? Do you have @phc/argon2 in your node_modules? I'm not to sure how lambda works with dependancies but it seems to have a problem loading a module.
