Description

hey,

i've been trying to deploy my smart contract on the hedera testnet account (ECDSA), followed all the steps mentioned in the readme.md file, all the environment variables have been set as mentioned but i still keep encountering this error.

when i run npx hardhat test the tests pass, but when i try to interact with the contract again gives me this error:

Issue

node uploadToHedera.js
OK till here Error interacting with contract: TypeError: Cannot read properties of undefined (reading 'publicKey') at NodeClient.setOperator (C:\Users\bawgi\OneDrive\Documents\DEHRSys\dehrsys\node_modules\@hashgraph\sdk\lib\client\Client.cjs:286:48) at interactWithContract (C:\Users\bawgi\OneDrive\Documents\DEHRSys\dehrsys\uploadToHedera.js:28:16) at Object.<anonymous> (C:\Users\bawgi\OneDrive\Documents\DEHRSys\dehrsys\uploadToHedera.js:44:1) at Module._compile (node:internal/modules/cjs/loader:1105:14) at Object.Module._extensions..js (node:internal/modules/cjs/loader:1159:10) at Module.load (node:internal/modules/cjs/loader:981:32) at Function.Module._load (node:internal/modules/cjs/loader:822:12) at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12) at node:internal/main/run_main_module:17:47

i believe the issue is occurring in the \node_modules\@hashgraph\sdk\lib\client\Client.cjs:286:48 file.

the code that is triggering the error:

const { Client, ContractCallQuery } = require("@hashgraph/sdk");

var contractAddress = "0x5c755dDFFBD0B6405DE612Bc96609d21C129917c";

async function interactWithContract(moralisHash) {
    try {
        const client = Client.forTestnet();
        console.log("OK till here")
        client.setOperator(process.env.ACCOUNT_ID, process.env.TESTNET_OPERATOR_PRIVATE_KEY);

        const contract = await new ContractCallQuery()
            .setContractId(contractAddress)
            .setGas(30000)
            .setFunction("changeHash")
            .addString(moralisHash)
            .execute(client);

        console.log("Transaction ID:", contract.transactionId);
    } catch (error) {
        console.error("Error interacting with contract:", error);
    }
}

const moralisHash = "https://ipfs.moralis.io:2053/ipfs/QmQvASqTFsJxNqym55KTm98FVWxwCD9cKt37ba6kYT962z/trainmedications.json";
interactWithContract(moralisHash);
