What's up?

I'm trying to make an RAW RPC call, it's working on my Network page I can see the request and the response, but the callback function of the web3.currentProvider.send method is returning error. I don't know why that's happening.

My code

    const getTransactionFromTo = async () => {
            let totalBlocks = await web3.eth.getBlockNumber();
            let transactions = [];
            for(let i = 0; i < 1; i++){
                web3.currentProvider.send({
                    jsonrpc: "2.0",
                    id: 1,
                    method: "eth_getBlockRange",
                    params: ["0x" + (totalBlocks-10).toString(16), "0x" + totalBlocks.toString(16), true]
                }, (err, res) => {
                    if (err) {
                        console.log(err)
                        console.log('res', res)
                        return;
                    }
    
                    const arrResult = res.result;
    
                    for(let i = 0; i < arrResult.length; i++){
                        let info = {};
                        let hour = new Date(arrResult[i].timestamp * 1000).getHours().toString();
                        info.hour = hour;
                        info.count = arrResult[i].transactions.length;
                        transactions.push(info);
                    }
                    resolve(transactions);
                });
                totalBlocks -= 1000;
            }
    };

I've just figured out what was happening.

I need to create promisses for every loop, then it resolved the issue.
