Error while deploying smart contracts with relayer

Support
1

Description

I was trying to use the defender-sdk along with hardhat-ethers, I manually created the relayer through the openzepplin website and got my relayerApiKey and relayerApiSecret. Then I tried to deploy the smart contract using relayer as signer. but I get issues with the following two lines of code

    const provider = client.relaySigner.getProvider();
    const signer = client.relaySigner.getSigner(provider, { speed: 'safeLow' });

and then the following error occurs

Error: Network error

  code: 'NetworkError'
}

    const client = new Defender(creds);
    const provider = client.relaySigner.getProvider();

    const cf = await ethers.getContractFactory("abc",signer)
