I found the bug may be sourced from the "Fetcher" in the "@Uniswap/SDK". After replaced the default provider "Fetcher" in the with the existing websocket provider, old errors disapeard were repalced by new errors subsequently. const {ethers} = require("ethers");
const {
ChainId,
Token,
TokenAmount,
WETH,
Fetcher,
Trade,
} = require("@uniswap/sdk");
// @ts-ignore
clientConfig: {
// Useful if requests are large
maxReceivedFrameSize: 100000000, // bytes - default: 1MiB
maxReceivedMessageSize: 100000000, // bytes - default: 8MiB
// Useful to keep a connection alive
keepalive: true,
keepaliveInterval: 60000, // ms
},
// Enable auto reconnection
reconnect: {
auto: true,
delay: 1000, // ms
maxAttempts: 10,
onTimeout: false,
},
};
const ws = new Web3WsProvider(
"wss://mainnet.infura.io/ws/v3/" + process.env.INFURA_URL,
options
);
const web3 = new Web3(ws);
const daiWeth_Pair = await Fetcher.fetchPairData(
dai,
weth,
new ethers.providers.Web3Provider(ws) // to replace the default provider.
);
Here is the old code. const {
ChainId,
Token,
TokenAmount,
WETH,
Fetcher,
Trade,
} = require("@uniswap/sdk");
// @ts-ignore
clientConfig: {
// Useful if requests are large
maxReceivedFrameSize: 100000000, // bytes - default: 1MiB
maxReceivedMessageSize: 100000000, // bytes - default: 8MiB
// Useful to keep a connection alive.
keepalive: true,
keepaliveInterval: 60000, // ms
},
// Enable auto reconnection.
reconnect: {
auto: true,
delay: 1000, // ms
maxAttempts: 10,
onTimeout: false,
},
};
const ws = new Web3WsProvider(
"wss://mainnet.infura.io/ws/v3/" + process.env.INFURA_URL,
options
);
// use default provider which is omitted here.
const web3 = new Web3(ws);
const daiWeth_Pair = await Fetcher.fetchPairData(
dai,
weth
);Here are the new errors: |

Fetcher was removed from this repository. Fetching data from the network to construct the classes in this repository is now the responsibility of a higher level library. The reason being, that different applications fetch data from the network in different ways (e.g. some may use in-memory caches, some may use multicall like the Uniswap interface, etc.) |
