分析

l1InfoTree.GetInitL1InfoRootMap 没有获取到数据
GetInitL1InfoRootMap 通过事件InitL1InfoRootMap进行写入的

if event.InitL1InfoRootMap != nil {
            log.Debugf("handle InitL1InfoRootMap event %s", event.InitL1InfoRootMap.String())
            err = processEventInitL1InfoRootMap(tx, block.Num, event.InitL1InfoRootMap)
            if err != nil {
                err = fmt.Errorf("initL1InfoRootMap. Err: %w", err)
                log.Errorf("error processing InitL1InfoRootMap: %v", err)
                return err
            }
        }

对应合约PolygonZkEVMGlobalExitRootV2.sol->emit InitL1InfoRootMap

 function initialize() external virtual initializer {
        // Get the current historic root
        bytes32 currentL1InfoRoot = getRoot();

        // Store L1InfoRoot
        l1InfoRootMap[uint32(depositCount)] = currentL1InfoRoot;

        emit InitL1InfoRootMap(uint32(depositCount), currentL1InfoRoot);
    }

继续排查，看链是否代码没有执行对应逻辑
l1infotreesync/processor.go

func (p *processor) ProcessBlock(ctx context.Context, block sync.Block) error {
    ...
        if event.InitL1InfoRootMap != nil {
            log.Debugf("handle InitL1InfoRootMap event %s", event.InitL1InfoRootMap.String())
            err = processEventInitL1InfoRootMap(tx, block.Num, event.InitL1InfoRootMap)
            if err != nil {
                err = fmt.Errorf("initL1InfoRootMap. Err: %w", err)
                log.Errorf("error processing InitL1InfoRootMap: %v", err)
                return err
            }
        }

func (d *EVMDriver) handleNewBlock(ctx context.Context, b EVMBlock) {
    ...
    err := d.processor.ProcessBlock(ctx, blockToProcess)

执行逻辑中已经包含 event.InitL1InfoRootMap

继续排查

排查两个角度

1. 合约中并未发出
2. 区块高度有错误

由于事件是由合约PolygonZkEVMGlobalExitRootV2.sol发出，对应的合约地址为deploy_output.json->polygonZkEVMGlobalExitRootAddress
查看当前地址
https://sepolia.etherscan.io/tx/0xc3b16bdaa7054689230e976e20badcb65c92ad2a623ea89b1b33147a1fc0f227#eventlog

高度：7085224
合约event.InitL1InfoRootMap已发出，排除问题1

继续看下配置的高度deploy_output.json->deploymentRollupManagerBlockNumber
https://sepolia.etherscan.io/tx/0x03f41442db2e20f2551436df6ec607be307c89e7b05fe32fc462fceb225ce24a
高度：7085226

问题汇总

当前高度没有包含PolygonZkEVMGlobalExitRootV2->initialize 高度，所以导致事件event.InitL1InfoRootMap没有扫描到，从而导致GetInitL1InfoRootMap数据没有本地存储，最终导致sequence-sender报错

解决方式

查询deploy_output.json->polygonZkEVMGlobalExitRootAddress合约地址交易对应的高度，并更新到sequence-sender配置
L1InfoTreeSync->InitialBlock
