Data has gone missing before, and was only fixed because I replaced the entry in the database and presently it has happned again but I have not yet looked if it can be reconstructed.
getTransaction API. The message body is missing from all nodes including archival nodes. If this piece was part of a NFT's image the data would be corrupted or completely missing if the first part of the chain requiring reassembly.
I can imagine that this could happen if, eg, the disk on which we upload the data has a full disk and therefore the data is corrupt at the source. Otherwise I agree it's a bug
This is not the first occurrence. Perhaps martis recalls the discussion we had on #developers about this same issue. In that case it was easy to discover the missing data because there were other copies with the same hash and I inserted the data into the platform, fortunately this did not mess up everyone's nodes. In the present case the sending account is Jelurida's and they posses the secret which can be used to help reconstruct the missing data. The next time perhaps the data will not be at all possible to recover.
So it means that the data can be lost also after long time after it has been uploaded? Or does this happen close to the upload time?
In the case discussed on #developers, the data does appear to have been lost at some point long after it was confirmed because the error did not show up before - although this may have been a change to the log detail.The present case the source is Jelurida's node reward account, so that it is odd that it has occurred from the developer's controlled account but convenient in that perhaps they can better investigate the issue and also they posses the source data to "fix" the missing database entry.In all cases the prunable data must have been broadcast and accepted to the block generator's node in order for the source transaction to have been confirmed.
The transaction hash can be found in a bundle transaction on a Jelurida node
But the transaction itself is "unkown" perhaps this detail will help the developers diagnose the issue.
This may be a serious issue because the non-prunable part of a money transfer transaction is missing so those nodes will not be able to rebuild and verify their blockchain.
