vmanage configuration database issue

Hi community, another post relating to issues bringing up vmanage in CML2. after waiting overnight, I now see some services running, but this error with bringing top the config database seems to be causing issues with a number of other services. There was a bug in v19 that is apparently fixed in 20.x (I'm running 20.13), and I can't see any other pointers to a fix. Any clues out there? Rewards for helpful hints!

neo4j log shows this error:
