same issue can anyone help

I researched the problem and it seems to be related to the 500 response from the IPFS provider in V2SubgraphProviderWithFallBacks.
SubgraphProvider makes a call to https://ipfs.io/ipns/api.uniswap.org/v1/pools/v2/mainnet.json and gets 500.

The same thing happens with V3.

Can anyone help with this?

@jsy1218 FYI

I hotfixed it by keeping the versions of the uniswap dependencies at a certain version.
It's not a very satisfying solution but the best we can do at this point.
You can find the versions here: https://github.com/JakobJar/uniswap-smart-router-rest/blob/master/package.json

I noticed that in the Ethereum network, routes are still founded through StaticV2SubgraphProvider.

The error is reproduced when trying to find routes in the Base network.

Using your versions I get the error:
Unexpected pool type in route when constructing trade object

Thank you for participating.
