Followed this doc to start the MPC key generation, but gives error while initializing FireblocksSDK with apiKey, privateKey
const secretKey = readFileSync(NCW_ADMIN_PRIVATE_KEY_PATH, "utf8");
const fireblocks = new FireblocksSDK({
apiKey: apiKey,
apiBaseUrl: "https://sandbox-api.fireblocks.io/v1", // or assign directly to "https://sandbox-api.fireblocks.io/v1";
privateKey: secretKey,
});
