AssertionError [ERR_ASSERTION]: you must provide a joi schema

[minnat]

I am writing a simple chargePoint that sends a websocket to the centralSystem. I took the code from the examples and this is where I am facing issues with:

    const boot = new OCPPCommands.BootNotification({
      chargePointVendor: 'BrandX',
      chargeBoxSerialNumber: 'SR' + Math.round(Math.random() * 100000),
      chargePointSerialNumber: '123',
      chargePointModel: '12'
    });

    let answer = await client.send(boot);

OCPPCommands.BootNotification tries to validate the payload with applyPropertiesValidators and it failed to validate with Joi, specifically on this line:

// node_modules/ocpp-eliftech/node_modules/joi/lib/index.js
Hoek.assert(schema && schema instanceof Any, 'you must provide a joi schema');

This is what schema looks like before it fails the schema instanceof Any validation:

I am not sure if this is a dependency issue or there is something missing on my side. Any help would be appreciated.
