DBCreator.py clear_and_generate command fails about bloodhound-tools HOT 2 CLOSED

It looks like this is caused by a timing issue. A sleep of three seconds before data generation solved it for me: https://github.com/BloodHoundAD/BloodHound-Tools/blob/master/DBCreator/DBCreator.py#L204

It seems like the database is busy with deleting the old nodes. This is what the docs state about transient errors:

Transaction functions are the recommended form for containing transactional units of work. This form requires minimal boilerplate code and allows for a clear separation of database queries and application logic.

and

Transaction functions are also able to handle connection problems and transient errors using an automatic retry mechanism. This retry capability can be configured on Driver construction.

I tried to find a clean solution by setting the retry time but it didn't work:

self.driver = GraphDatabase.driver(self.url, auth=(self.username,self.password), max_retry_time=15)
