Unable to fetch pair data using uniswap V2. Error in getReserves()

[Rajwanshi]

Hi Team,

I am getting error while calling fetchPairData().

Error: call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="getReserves()", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.6.4)

Tried calling this on ropsten and hardhat local network(mainnet forked). From the local hosted test net, I can see that the target address is not a contract address and hence the call is failing.

Logs from the local testnet console:

WARNING: Calling an account which is not a contract
From: 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
To: 0x80e8c5d88743c4e77259d2be6442190af366d723

Could you please help me with resolving the above issue. Any help would be very much appreciated :)

Thanks!

Hi @Rajwanshi ,

What version of the sdk are you using? The Fetcher class was removed in version 1.0.2. of the v2-sdk so I suppose you are using the deprecated uniswap-sdk package.
The Factory address and Init code hash were changed in version 2.0.0 of the uniswap-sdk package, if you are using an older version the getCreate2Address function would return a different address.

In any case, I would suggest not using the Fetcher class and using the v2-sdk package instead of uniswap-sdk:
https://www.npmjs.com/package/@uniswap/v2-sdk
Please let me know if you also experience this issue (getting the wrong contract address) with the current V2 SDK.
