Question

Hello guys,
I installed required dependencies in my Angular dApp as described in the README:

npm install --save-dev ethers reflect-metadata
npm install @aave/contract-helpers @aave/math-utils

I coded the following typescript function

import { UiIncentiveDataProvider } from '@aave/contract-helpers';

getReservesIncentivesDataHumanized() {

    const incentiveDataProviderContract = new UiIncentiveDataProvider({
        // UiIncentiveDataProviderV3: From AAVE V3 deployed contracts page
        uiIncentiveDataProviderAddress:  '0x270f51cf3F681010B46f5c4Ee2aD5120Db33026F',
        provider: this.provider,
        chainId: chainId
    });

    return incentiveDataProviderContract.getReservesIncentivesDataHumanized(
        {
           // PoolAddressesProvider: From AAVE V3 deployed contracts page
            lendingPoolAddressProvider: '0xa97684ead0e402dC232d5A977953DF7ECBaB3CDb' 
        }
    );
}

However when I try to compile my application I get a bunch of errors reporting some missing dependencies:

Error: node_modules/@aave/contract-helpers/dist/cjs/baseDebtToken-contract/index.d.ts:5:32 - error TS2307: Cannot find module './typechain/IDebtTokenBase' or its corresponding type declarations.

Error: node_modules/@aave/contract-helpers/dist/cjs/erc20-contract/index.d.ts:4:32 - error TS2307: Cannot find module './typechain/IERC20Detailed' or its corresponding type declarations.

Error: node_modules/@aave/contract-helpers/dist/cjs/erc20-2612/index.d.ts:3:28 - error TS2307: Cannot find module './typechain/IERC202612' or its corresponding type declarations.

I tried to import UiIncentiveDataProvider also from other locations:
import { UiIncentiveDataProvider } from '@aave/contract-helpers/dist/esm';
import { UiIncentiveDataProvider } from '@aave/contract-helpers/dist/cjs';
but I get the very same result.

Is there something wrong in my approach?

Thank you very much.

I'm running into similar issues when I attempt to compile just importing of the contract-helper modules:

import {
  UiPoolDataProvider,
  UiIncentiveDataProvider,
  ChainId,

Hey @simeoni3 @peterfisher - just for context, can you provide what version of Angular your dapp is using? Also, can you provide what version of TypeScript, if any, you are running as well? Thanks!

[bravura-quark]

+1 on this.
My typescript version is 4.1.3
I am using this utility from a nodejs backend application.
Do we have any workaround to get this running?

@simeoni3 @bravura-quark @peterfisher @malsamax
Hi there!
I've found a fix, that we've all missed — it's tsconfig configuration issue.

To fix this, add this to your tsconfig.json:
"skipLibCheck": true

Learn more about this option here: https://www.typescriptlang.org/tsconfig#skipLibCheck

It worked out fine, and I hope that helps you guys too

Cheers

[drewcook]

That would make sense! https://github.com/aave/aave-utilities/blob/master/tsconfig.json#L21C5-L21C26
