You need to add a mode: ‘cors’ attribute inside the API callback function

I’ve already added it

```auto
const response2 = await axios.post(Bitquery.endpoint, {
                query: `
                        {
                          ethereum(network: bsc) {
                            dexTrades(
                              options: {asc: "timeInterval.minute"}
                              date: {since: "2021-06-20T07:23:21.000Z", till: "${new Date().toISOString()}"}
                              exchangeAddress: {is: "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73"}
                              baseCurrency: {is: "${baseCurrency}"},
                              quoteCurrency: {is: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c"},
                              tradeAmountUsd: {gt: 10}
                            ) 
                            {
                              timeInterval {
                                minute(count: 15, format: "%Y-%m-%dT%H:%M:%SZ")  
                              }
                              volume: quoteAmount
                              high: quotePrice(calculate: maximum)
                              low: quotePrice(calculate: minimum)
                              open: minimum(of: block, get: quote_price)
                              close: maximum(of: block, get: quote_price) 
                            }
                          }
                        }
                        `,
                variables: {
                    "from": new Date("2021-06-20T07:23:21.000Z").toISOString(),
                    "to": new Date("2021-06-23T15:23:21.000Z").toISOString(),
                    "interval": Number(resolution),
                    "tokenAddress": symbolInfo.ticker
                },
                mode: 'cors',
                headers: {
                    "Content-Type": "application/json",
                    "X-API-KEY": "BQYyGwlM3uQRKbNrPS01UwFpoDHrTaEq"
                }
            })

```

but the problem remains
