Error: error code: 1016

[easonchan17]

why recv Error: error code: 1016 when call await renVM.queryBlockState(asset, 5) . provider is https://rpc-testnet.renproject.io.
code:

import { providers, Wallet } from "ethers";

import { Bitcoin, Ethereum } from "@renproject/chains";
import { RenJS } from "@renproject/ren";

// Test account - do not send real funds.
const mnemonic =
    "black magic humor turtle symptom liar salmon rally hurt concert tower run";
const network = "testnet";

const main = async () => {
    // Initialize Bitcoin and Ethereum.
    const bitcoin = new Bitcoin({ network });
    const ethereum = new Ethereum({
        network,
        provider: new providers.JsonRpcProvider(
            Ethereum.configMap[network].config.rpcUrls[0]

    });

    // Create RenJS instance. NOTE - chains must now be linked to RenJS using
    // `withChains`.
    const renJS = new RenJS(network).withChains(bitcoin, ethereum);
//    console.log('renJS', renJS)

    // Create gateway - mints and burns are both initialized with `gateway`.
    // Gateway parameters are serializable.
    const gateway = await renJS.gateway({
        asset: bitcoin.assets.BTC, // "BTC"
        from: bitcoin.GatewayAddress(),

    // `gateway.fees` exposes values and helpers for calculating fees.
    console.log(gateway.fees);

    console.log(`Deposit ${gateway.params.asset} to ${gateway.gatewayAddress}`);

            console.log(tx.params);

            // Wait for remaining confirmations for input transaction.
            await tx.in.wait();

            // RenVM transaction also follows the submit/wait pattern.
            await tx.renVM.submit().on("progress", console.log);
            await tx.renVM.wait();

            // `submit` accepts a `txConfig` parameter for overriding

                txConfig: {
                    gasLimit: 1000000,
                },
            });
            await tx.out.wait();

            // All transactions return a `ChainTransaction` object in the
            // progress, with a `txid` field (base64) and a `txidFormatted`
            // field (chain-dependent).
            const outTx = tx.out.progress.transaction;
            console.log("Done:", outTx.txidFormatted);

            // All chain classes expose a common set of helper functions (see
            // `Chain` class.)
            console.log(tx.toChain.transactionExplorerLink(outTx));
        })().catch(console.error);
    });
};

main().catch((error) => {
    console.error(error);
    process.exit(1);
});

Also, is there a Discord channel to discuss encountered issues?
