CCXT.pro Issue with Coinbasepro watchOrderBook with limit

See original GitHub issue

OS: Windows
Programming Language version: node.js V14.16
CCXT version: CCXT.pro 1.0.21

Watching coinbasepro orderbook with a limit defined causes an error handling updates from coinbase. This was not an issue in ccxt.pro version 1.0.15.

const ccxtpro = require('ccxt.pro');
console.log(ccxtpro.version);

(async () => {
    const exchange = new ccxtpro.coinbasepro()
    const orderbook = await exchange.watchOrderBook('BTC/USD', 25)
    console.log(new Date(), orderbook['asks'][0], orderbook['bids'][0])
}
)()

@kroitor in my quick test, everything looks good. If any issues arise I’ll circle back.
