noticing the JS api does not surface errors verbosely

[rrshaban]

const { restClient } = require('@polygon.io/client-js');
const rest = restClient("API KEY"); // actual code


rest.stocks.aggregates("AAPL", 1, "day", "2023-01-01", "2019-04-14").then((data) => {
	console.log(data);
}).catch(e => {
	console.error('An error happened:', e);
});

// last trade
rest.stocks.lastTrade("AAPL").then((data) => {
	console.log(data);
}).catch(e => {
	console.error('An error happened:', e);
});

// last quote (NBBO)
rest.stocks.lastQuote("AAPL").then((data) => {
	console.log(data);
}).catch(e => {
	console.error('An error happened:', e);
});


rest.stocks.snapshotAllTickers().then((data) => {
	console.log(data);
}).catch(e => {
	console.error('An error happened:', e);
});

It would be lovely if "T [Error]" offered some kind of ... error type . or message. as it is, the error was No api key, but how could I know?

noting that when I do add the ApiKey, I get 400s and 403... hmm...

NB: having tried 4 of the tutorials now, none of them seem to be "working as-is" with the beginner (Free) api key.
