Flowable - MongoDB Standalone

Flowable Engine
1

Hi Team,
The github project GitHub - flowable/flowable-mongodb suggests to use mongodb replica set. But we have requirement to use Standalone mongodb.
When I tried to use standalone mongodb I got the following error.
‘Transaction numbers are only allowed on a replica set member or mongos’

Can you suggest if there is a way to use standalone mongodb with flowable engine?

Regards,
Venkat

As described in the readme there, it is alpha/prototype software. Back when it was implemented, transactions on MongoDB only worked on replica sets. Looking quickly at the docs, seems to indicate this is still the case. The Flowable engine does need transactions to guarantee correct functioning.
