HDWalletProvider 升级到 1.3.x 之后，只能对以太坊网络进行比较好的支持，并且需要显式指定 chainId。对于非以太坊网络比如当下比较热门的 heco/bsc，在官方解决到相应问题之前，还是保持在 1.2.x 版本比较好。

最近在使用 truffle 往 heco 上部署合约时，突然就碰到了一个之前没碰到过的错误：

多方查证，原来是最新版的 HDWalletProvider (版本 1.3.1) 需要指定 chainId

于是乎将将原来的写法：

provider: () => new HDWalletProvider(mnemonic, `wss://ws-testnet.hecochain.com`)

改为了下面这种形式：

provider: () => new HDWalletProvider({
        privateKeys: [mnemonic],
        providerOrUrl: `wss://ws-testnet.hecochain.com`,
        chainId: 256
      }),

但还是报错 "Error: Chain with ID 256 not supported", 原来这个版本只支持以太坊主网和测试网的 chainId，官方已经在这里记下了这个问题并在着手修复。

直接将HDWalletProvider版本调整到 1.2.6, 问题得以解决。
