Bloodhound / Sharphound - How is this used?

Hello, I have also an issue with the bloodhound part.

I use the following command which works:
kali@kali:~/Downloads/blood_attack$ python3 -m bloodhound -d megacorp.local -u sandra -p “Password1234!” -gc pathfinder.megacorp.local -c all -ns 10.10.10.30
INFO: Found AD domain: megacorp.local
INFO: Connecting to LDAP server: Pathfinder.MEGACORP.LOCAL
INFO: Found 1 domains
INFO: Found 1 domains in the forest
INFO: Found 1 computers
INFO: Connecting to LDAP server: Pathfinder.MEGACORP.LOCAL
INFO: Found 5 users
INFO: Connecting to GC LDAP server: pathfinder.megacorp.local
INFO: Found 51 groups
INFO: Found 0 trusts
INFO: Starting computer enumeration with 10 workers
INFO: Querying computer: Pathfinder.MEGACORP.LOCAL
INFO: Done in 00M 05S

But when i drag & drop json files in bloodhound i have always:
NO DATA RETURNED FROM QUERY

I use bloodhound 3.0.4 on a kali debian 2020.2
Python 3.8.3 and neo4j 4.1.0

I don’t see any link between nodes and the only query working is “List all Kerberoastable Accounts”.

Do you know what is wrong ?

Thanks !
