Why get transactions from blockExtra miss data? How to get all the unpruned transactions data via blockExtra

[fishTsai20]

Using liteserver.getBlock to get Block data, the I load Cell from BlockExtra, after some steps I get transactions. But the transactions count is not right. Such as seqNo: 39789259 in MasterChain. The count of transactions I got is 2, which is not equal with 3. https://tonscan.org/block/-1:8000000000000000:39789259

3. get ShardAccountBlocks from BlockExtra
