[英]cannot approve contract to ERC-20 token due to ProviderError: HttpProviderError error
OracleSwap is a DEX that is a fork of Uniswap. OracleSwap 是一个 DEX,它是 Uniswap 的一个分支。
The end goal is I am trying to add liquidity https://docs.uniswap.org/contracts/v2/reference/smart-contracts/router-01#addliquidity最终目标是我正在尝试增加流动性https://docs.uniswap.org/contracts/v2/reference/smart-contracts/router-01#addliquidity
In order to do this, first we need to approve the OracleSwapRouter contract to spend the erc20 token.为此,首先我们需要批准 OracleSwapRouter 合约使用 erc20 代币。
I get below error when I am trying to approve
to OracleSwapRouter
in songbird (EVM compatible) network so that I can provide liquidity on the farm.当我试图
approve
OracleSwapRouter
(EVM 兼容)网络中的 OracleSwapRouter 以便我可以在农场提供流动性时,我遇到了以下错误。 I am not sure if this is an RPC rate-limiting issue or if something is wrong with the code.我不确定这是 RPC 速率限制问题还是代码有问题。

Below are the relevant code snippets下面是相关的代码片段
const OracleSwapRouterContract = await ethers.getContractAt(OracleSwapRouterAbi.default,
"0x73E93D9657E6f32203f900fe1BD81179a5bf6Ce4");
const oracleContract = await ethers.getContractAt(oracleAbi.default, "0xd7565b16b65376e2ddb6c71e7971c7185a7ff3ff");
await oracleContract.approve(
"0x73E93D9657E6f32203f900fe1BD81179a5bf6Ce4",
oracleBalance
);
The below code gives me the balance for the account so I know oracleContract is not the problem.下面的代码给了我账户余额,所以我知道 oracleContract 不是问题所在。
const oracleBalance = await oracleContract.balanceOf(SONGBIRD_ACC);

You can add some lines to node_modules/hardhat/internal/core/providers/http.js to debug.您可以将一些行添加到 node_modules/hardhat/internal/core/providers/http.js 进行调试。 After every isErrorResponse check, add: console.log(response) or console.log(jsonRpcResponse).
在每个 isErrorResponse 检查之后,添加:console.log(response) 或 console.log(jsonRpcResponse)。
Most likely it's an error inside your contracts or deploy script (or both).这很可能是您的合同或部署脚本(或两者)中的错误。
