I posted a question before, in which I was told that UiPoolDataProvider and UiIncentiveDataProvider should deploy V2V3 version and now deploy V2V3 version

I cloned the interface repo locally and changed the address corresponding to kovan

  [CustomMarket.proto_kovan]: {
    marketTitle: 'Ethereum Kovan',
    chainId: ChainId.kovan,
    enabledFeatures: {
      governance: true,
      staking: true,
      incentives: true,
    },
    rpcOnly: true,
    addresses: {
      LENDING_POOL_ADDRESS_PROVIDER: '0x937E72Fb6Fc133D2CF437d65B3AD7E4C613c3C7E'.toLowerCase(),
      LENDING_POOL: '0x25971b0364c4d4eeE145ebc7255973561CDd8232',
      WETH_GATEWAY: '0x9A04494965A8a8EA9844D798f9ACC69B0456AAa6',
      WALLET_BALANCE_PROVIDER: '0xFE2413d89371d9478f477236c64be5c02dA1af5F',
      UI_POOL_DATA_PROVIDER: '0x27211785F1ED5489337040f67584CCb508b61a2D',
      UI_INCENTIVE_DATA_PROVIDER: '0x35a305eD9737B2AeE68FF90e1Bce84fA1137E0dF',
    },
  },

then I open the browser, visit: http://localhost:3000/ and switch to the test network, there is the following error prompt

the error is the code of usePoolDataRPC.tsx

const reservesResponse = await poolDataProviderContract.getReservesHumanized({
  lendingPoolAddressProvider,
});

the error comes from the getReservesData method

const { 0: reservesRaw, 1: poolBaseCurrencyRaw }: ReservesData =
  await this.getReservesData({ lendingPoolAddressProvider });

but my call from browser is successful

I don't understand why there is such a problem, please help me, it is difficult for me to read the contract code without the interface

The contract-helpers library uses a single version of the UiPoolDataProvider and UiIncentiveDataProvider for all markets (V2 and V3). The current version used by all markets on the interface is from this commit: https://github.com/aave/aave-v3-periphery/blob/b04d26e91cb8d795ccd75eba44fc0f350180debf/contracts/misc/UiPoolDataProviderV3.sol

Sorry, I don't understand very well, do you mean that I need to deploy an aave-v3-periphery contract to replace the original UiPoolDataProvider and UiIncentiveDataProvider?

That's what I was intending when I wrote the comment, but actually looking at this contract the constructor doesn't take any market-specific parameters so you can just use the existing contract on Kovan.

If you replace the UI_POOL_DATA_PROVIDER and UI_INCENTIVE_DATA_PROVIDER addresses in your marketConfig with the addresses linked here it should work.

Thanks, I use the original UI_POOL_DATA_PROVIDER and UI_INCENTIVE_DATA_PROVIDER addresses, it works normally and no error is reported, but when I try to pledge, he has an unknown error, I don't understand if it is related to UI_POOL_DATA_PROVIDER, UI_INCENTIVE_DATA_PROVIDER

What's the error message?

If it contains SERVER_ERROR it's most likely an RPC issue. The Kovan network is technically deprecated, so the RPCs are very unreliable.

I found no errors on chroma's console or on the network, only the UI has a reminder, I suspect it is a contract problem, but I can't deploy aave-v3-periphery now, because it relies on @aave/deploy-v3 this private repo, I don't have permission to access.....
