尝试运行时truffle migrate --network bsc，松露通常（并非总是）设法部署迁移合同，然后失败并出现错误：找不到标头。

Error [ERR_UNHANDLED_ERROR]: Unhandled error. ({ code: -32000, message: 'header not found' })

这是 bsc 网络的配置：

   bsc: {
      provider: () => { return new HDWalletProvider(mnemonic, `https://bsc-dataseed2.binance.org/`)},
      network_id: 56,
      confirmations: 10,
      timeoutBlocks: 200,
      skipDryRun: true,
    },

 compilers: {
    solc: {
      version: "0.8.7",    // Fetch exact version from solc-bin (default: truffle's version)
      // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
      settings: {          // See the solidity docs for advice about optimization and evmVersion
       optimizer: {
         enabled: true,
         runs: 200
       },

部署到测试网和开发工作没有问题。我过去曾用松露部署到 bsc（虽然已经有一段时间了）。我尝试过更改 RPC url，并搞砸了超时和确认（很确定这对这个错误没有影响）。在互联网上搜索解决方案后，似乎对人们有用的唯一答案是更改 RPC，但我没有任何运气。有没有人有什么建议？

我今天遇到了同样的问题。通过使用智能链文档https://docs.binance.org/smart-chain/developer/rpc.html中的 Websocket 端点 wss://bsc-ws-node.nariox.org:443 修复它
