Open fishTsai20 opened 3 weeks ago

fishTsai20 commented 3 weeks ago

var ab tlb.AccountBlock if err = tlb.LoadFromCell(&ab, slc); err != nil { return fmt.Errorf("faled to parse account block: %w", err) } addr := address.NewAddress(0, byte(0), ab.Addr) log.Info("account block's ", zap.Any("address", addr)) //state_update:^(HASH_UPDATE Account) update := ab.StateUpdate.BeginParse() var stateUpdate tlb.HashUpdate err = tlb.LoadFromCell(&stateUpdate, update) if err != nil { log.Error("failed to get stateUpdate of account", zap.Any("address", addr), zap.Error(err)) return err }

failed to get stateUpdate of account {"address": "EQAzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzM7SN", "error": "magic is not correct for tlb.HashUpdate, want #72"}

Hi, it looks like a different data inside ab.StateUpdate, you can do println(ab.StateUpdate.Dump()) to check, maybe it is pruned (collapsed part of merkle proof)

Isn't your type definition consistent with TON's? https://github.com/ton-blockchain/ton/blob/24dc184a2ea67f9c47042b4104bbb4d82289fac1/crypto/block/block.tlb#L231-L233 How do I parse this StateUpdate ?
