granularity argument is invalid

[JoshMayberry]

I cannot use this sdk to get candles.
Doing this:

const request = {
	productId: "DOGE-USDC",
	start: "1743800924",
	end: "1743804524",
	granularity: "FIVE_MINUTE",
	limit: 300,
};
const response = await productService.getProductCandles(request);

Throws the error 400 Coinbase Invalid Request Error: Request failed with status code 400 granularity argument is invalid

I verified that the url it generates is https://api.coinbase.com/api/v3/brokerage/products/DOGE-USDC/candles?start=1743800924&end=1743804524&granularity=FIVE_MINUTE&limit=300.

In contrast, I am able to get it without using this library like this:

import fetch from 'node-fetch';
import crypto from 'crypto';
import jwt from 'jsonwebtoken';

function buildJWT(uri: string) {
	const privateKey = process.env.COINBASE_API_SECRET;
	if (!privateKey) {
		throw new Error("Missing secret");
	}
	
	const payload = {
		sub: process.env.COINBASE_API_KEY,
		iss: 'cdp',
		nbf: Math.floor(Date.now() / 1000),
		exp: Math.floor(Date.now() / 1000) + 120,
		uri: uri,
	};
	
	const token = jwt.sign(payload, privateKey, {
		algorithm: 'ES256',
		header: {
		kid: process.env.COINBASE_API_KEY,
		nonce: crypto.randomBytes(8).toString('hex'),
		} as any,
	});
	
	return token;
}
	
async function fetchCandles(productId: string, start: number, end: number) {
	const uri = `GET api.coinbase.com/api/v3/brokerage/products/${productId}/candles`;
	const jwtToken = buildJWT(uri);
	
	const params = new URLSearchParams({
		start: String(start),
		end: String(end),
		granularity: 'FIVE_MINUTE',
		limit: '300',
	});
	
	const url = `https://api.coinbase.com/api/v3/brokerage/products/${productId}/candles?${params.toString()}`;
	
	const headers = {
		'Authorization': `Bearer ${jwtToken}`,
		'Content-Type': 'application/json',
	};
	
	const response = await fetch(url, { method: 'GET', headers });
	
	console.log('Status:', response.status);
	console.log('URL:', response.url);
	
	const body = await response.text();
	console.log('Response:', body);
}

router.get("/test", (req: express.Request, res: express.Response) => {
	const now = Math.floor(Date.now() / 1000);
	const start = now - 3600;
	const end = now;
	
	fetchCandles('DOGE-USDC', start, end).catch(console.error);
	res.send("Done")

});

It seems that others have had this issue when their request if not formatted perfectly.

I think there might be something in the way that requests are being made that the products/${productId}/candles endpoint does not like.

Hi Josh, thank you for the report. This has been fixed in the 0.2 release. There was an issue with query parameter encoding that was fixed.
