I have an application spring boot and spring data, i tried to use mongock and i configure it like below

mongock:
  migration-scan-package:
    - com.digital.ecom.config.dbmigrations
  transaction-enabled: true

but when i run the application i have this error

Caused by: com.mongodb.MongoCommandException: Command failed with error 20 (IllegalOperation): 'Transaction numbers are only allowed on a replica set member or mongos' on server 127.0.0.1:27017. The full response is {"ok": 0.0, "errmsg": "Transaction numbers are only allowed on a replica set member or mongos", "code": 20, "codeName": "IllegalOperation"}
spring boot: 2.7.1
mongock: 5.1.3

Hello @akanzari ,

That MongoDB error(not related to Mongock) is because MongoDB transactions are only allowed with replica-sets.

In this sample project we show how to do it and in the requirement section yo can see how to locally setup a MongoDB replica set environment with docker compose.

I hope this helps 😃
