Under some circumstances, it is possible that your database Dump produced from some old version of the Neo4j database fails to load successfully due to a defect in the underlying database archive produced.
The issue usually only affects the metadata and on loading to AuraDB (currently running on Neo4j version 4). it fails a check (to ensure complete data and metadata integrity) and this is when you should proceed as follows:
1 - Download a Neo4j Enterprise 4.4.x latest via Neo4j Desktop
2 - Start the local database and run :
3 - Download a Dump from AuraDB or create a local neo4j database dump that you want to import into AuraDB.
4 - Locally, load the Dump file from Aura you have downloaded or the dump file you have created from the local neo4j database.
