:1234: Code to reproduce

I'm creating a signature with _signTypedData

my node js code:

const { ethers } = require("ethers");

exports.cashmereBridge = async (contract,signer,provider) => {

    const currentDate = new Date()
    console.log(currentDate.toLocaleString())

    const gasPrice = await provider.getGasPrice()
    const gasLimit = ethers.BigNumber.from(4000000)

    const srcToken = "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee"
    const srcAmount = ethers.utils.parseEther('0.1')
    const lwsPoolId = 1
    const hgsPoolId = 1
    const dstToken = "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee"
    const dstChain = 10160
    const dstAggregatorAddress = '0x9b9f55494cf915c728dc65ee113c7309ee16ca18'
    const minHgsAmount = '76026680535845117664'
      
    const domainSeparator = {
        name: "Parameters",
        version: "1",
        chainId: "59140",
        verifyingContract: "0x76303b0C86Ec887867e22E44a681bDbCaE85Ccdf",
    }
      
    const types = {
        Parameters: [
          { name: "receiver", type: "address" },
          { name: "lwsPoolId", type: "uint16" },
          { name: "hgsPoolId", type: "uint16" },
          { name: "dstToken", type: "address" },
          { name: "minHgsAmount", type: "uint256" },
        ],
    }

    const message = {
        receiver: signer.address,
        lwsPoolId: lwsPoolId,
        hgsPoolId: hgsPoolId,
        dstToken: dstToken,
        minHgsAmount: minHgsAmount,
    }
      
    const signature = await signer._signTypedData(domainSeparator, types, message);
  
    const params = [
        srcToken,
        srcAmount,
        lwsPoolId,
        hgsPoolId,
        dstToken,
        dstChain,
        dstAggregatorAddress,
        minHgsAmount,
        signature
    ]
    console.log(params)

    const overrides = {
      gasPrice: gasPrice,
      gasLimit: gasLimit,
      from: signer.address,
      value: ethers.utils.parseEther('0.13'),
    }

    try {
        const tx = await contract.startSwap(
            params,
            overrides,           
        )
    
        const receipt = await tx.wait()
        console.log(signer.address,'cashmere transaction confirmed:',receipt.transactionHash) 
    } catch (error) {
        console.log(signer.address,'error sending cashmere transaction:',error)
    }
}

however, getting into this contract (0xFe1D2647be6e9542e96528EBb3B44E5bE035c85C), it is rejected

require(
            _hashTypedDataV4(
                keccak256(
                    abi.encode(
                        keccak256(
                            "Parameters(address receiver,uint16 lwsPoolId,uint16 hgsPoolId,address dstToken,uint256 minHgsAmount)"
                        ),
                        msg.sender,
                        params.lwsPoolId,
                        params.hgsPoolId,
                        params.dstToken,
                        params.minHgsAmount
                    )
                ),
                block.chainid,
                address(this)
            ).recover(params.signature) == msg.sender,
            "!signature"
        );

I will be glad of any help

Please provide more details. What is the contract that will be verifying and accepting the signature? You mentioned 0xFe1D2647be6e9542e96528EBb3B44E5bE035c85C but in your JavaScript code it says verifyingContract: "0x76303b0C86Ec887867e22E44a681bDbCaE85Ccdf".
