Tradingview changed some metadata and even get private indicator doesn't work.

`const TradingView = require('@mathieuc/tradingview');

/**

• This example creates a chart with all user's private indicators
  */

process.argv[2] = "gkxr8eu7va2mgfdvcOMITED"
process.argv[3] = "v3:hR+9bFzBLoHRuCOMITED"
//const id = "7pxbwffocii753w2z5jjdq0xf3jb0kri";
//const certificate = "v3:BwppgofWBHNGegxr2nX7Za9neYzpMP7hzqaW71vx3xk=";
if (!process.argv[2]) throw Error('Please specify your 'sessionid' cookie');
if (!process.argv[3]) throw Error('Please specify your 'signature' cookie');

const client = new TradingView.Client({
token: process.argv[2],
signature: process.argv[3],
});

const chart = new client.Session.Chart();
chart.setMarket('BINANCE:BTCEUR', {
timeframe: 'D',
});

TradingView.getPrivateIndicators(process.argv[2]).then((indicList) => {
indicList.forEach(async (indic) => {

try {
  const privateIndic = await indic.get();
  console.log('Loading indicator', indic.name, '...');
  const indicator = new chart.Study(privateIndic);
  indicator.onReady(() => {
    console.log('Indicator', indic.name, 'loaded !');
  console.log('Indicator', indic.id, 'id !');
  console.log('Indicator', indic.version, 'version !');
  console.log('Indicator', indic.type, 'type !');
  console.log('Indicator', indic.source, 'source !');
  });
}
catch (error) {
  console.error('Error:', error.message);
}


// indicator.onUpdate(() => {
//   console.log('Plot values', indicator.periods);
//   console.log('Strategy report', indicator.strategyReport);
// });

});
});
`

Here is result:
