Description
### Search before asking
- [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
### Paimon version
paimon 1.1.1 +flink 1.18
Basically, all the trigger conditions are met:
1. DEBUG logging was enabled for org.apache.paimon.flink.lookup.FileStoreLookupFunction in the production environment.
2. A lookup join is being used, and the table created is a SecondaryIndexLookupTable.
3. The join key is contract_no, which is not the complete primary key. The logs show _KEY_contract_no and _KEY_reg_valid, indicating that the full key also involves reg_valid.
4. There is a mismatch in the field order among the lookup projection, Paimon's internal read schema, and the original table schema.
5. The DEBUG branch attempts to print the matched rows, which leads to the execution of logRow().

### Compute Engine
flink 1.18
### Minimal reproduce step
1. DEBUG logging was enabled for org.apache.paimon.flink.lookup.FileStoreLookupFunction in the production environment.
2. A lookup join is being used, and the table created is a SecondaryIndexLookupTable.
3. The join key is contract_no, which is not the complete primary key. The logs show _KEY_contract_no and _KEY_reg_valid, indicating that the full key also involves reg_valid.
4. There is a mismatch in the field order among the lookup projection, Paimon's internal read schema, and the original table schema.
5. The DEBUG branch attempts to print the matched rows, which leads to the execution of logRow().

Commencez par FileStoreLookupFunction.lookup et suivez lookupInternal jusqu’au chemin de journalisation DEBUG qui appelle logRow(). Reproduisez le problème avec un lookup join Flink 1.18 sur une SecondaryIndexLookupTable, une clé contract_no partielle et la journalisation DEBUG activée. C’est terminé lorsque le lookup n’échoue plus avec IndexOutOfBoundsException lors de la journalisation des lignes correspondantes.
