error creating aggregate: sub-deals are too large to fit in the index

[longfeiWan9]

Setup for xchainClient:

• setting "TargetAggSize": 4194304 (4MB) in config.json
• run xchainClient with buffer and aggregation

  ./xchainClient daemon --config ./config/config.json --chain avalanche --buffer-service --aggregation-service
  

• run xchainClient to upload a file that is around 1.2MB
  • success uploaded and invoke smart contract on Avalanche
  • event log is emitted and cought by the xchainClient daemon.
  • file paddedSize is 2097152 which is smaller than targged Aggregation size.
• Received the error below

  error creating aggregate: sub-deals are too large to fit in the index: 4194304 (packed subdeals) + 2048 (index) > 4194304 (dealSize)
  

From my understanding, padded piece size is smaller than the targeted aggregation size and it should wait for more files. But I might misunderstand something.
