ERROR: chunk size exceeds buffer size while exporting monero database
Hi!

I wanted to create a backup of my monero database and found the tool monero-blockchain-export.exe.
Yesterday, i let the tool run for a few minutes and it all worked very well.

But when i want to restart the backup, i get a "chunk size exceeds buffer size" error.
I have synced the database in between these two export attempts, could this be the problem? If yes, isn't this tool supposed to make incremental backups easier?

My blockchain.raw export file is currently ~9GB and at about block height ~1.300.000
