Virgil SDK 6.1.2 Type Error in Node v16.13.1

[supertopoz]

[Context]
I'm building a small server to collect JWT tokens. The route handling looks below. When the server runs there is a TypeError from the Virgil-SDK

RuntimeError: abort(TypeError: Invalid format of 'Data'.). Build with -s ASSERTIONS=1 for more info.
at process.B (/Users/MY_USER_NAME/Documents/sendbird-virgil-uikit-sample/server/node_modules/@virgilsecurity/core-foundation/node.cjs.js:1:2501)

[Environment]
MAC Pro - Monterey - Intel not M1
Node v16.13.1
npm v8.1.2

[Impact]
I'm working to write a guide for Virgil security and Sendbird. However, I'm stuck at the moment as it seems that Node.js above v13 (two years old) is not supported

My jwt route example:

`
import express from 'express';
import { JwtGenerator } from 'virgil-sdk';

import {
initCrypto,
VirgilCrypto,
VirgilAccessTokenSigner,
} from 'virgil-crypto';

const getJwtGenerator = async () => {

await initCrypto();
const virgilCrypto = new VirgilCrypto();
return new JwtGenerator({
appId: process.env.VIRGIL_APP_ID,
apiKeyId: process.env.VIRGIL_APP_KEY_ID,
apiKey: virgilCrypto.importPrivateKey(process.env.VIRGIL_APP_KEY),
accessTokenSigner: new VirgilAccessTokenSigner(virgilCrypto),
});

};

const generatorPromise = getJwtGenerator();

export const virgilRouter = express.Router();

virgilRouter.get('/jwt/:userId', async (req, res) => {

const generator = await generatorPromise;
const virgilJwtToken = generator.generateToken(req.user.identity);
console.log({ virgilToken: virgilJwtToken.toString() });
res.json({ virgilToken: virgilJwtToken.toString() })

`});``

Hello @supertopoz ! You do not need to virgilCrypto.importPrivateKey(process.env.VIRGIL_APP_KEY)! This mrthod needs for encrypt and decrypt. Just set apiKey: process.env.VIRGIL_APP_KEY. Should help your ptoblem!

The readme suggests using node 10-13 https://github.com/VirgilSecurity/demo-backend-nodejs.

I had a similar issue and downgraded to node 12 to get this example to work.
