Unable to create flexible privacy group with Besu version >= 22.10.0

[ghost]

Description

We were trying to create flexible privacy group between two parties. While creating privacy group, we observed an error "Returned error: Flexible Privacy group does not exist".

This behavior is only observed for Besu's version >= 22.10.0 (including latest).

Note: It is working fine with Besu's version 22.7.7.

Steps to Reproduce (Bug)

1. Create a flexible privacy group between two parties using web3js-quorum method: web3.eth.flexiblePrivacyGroup.create

Logs (if a bug)

1. Error observed from client: Flexible Privacy group does not exist.

Versions (Add all that apply)

• Software version: Besu >= 22.10.0
• Added Configuration: --privacy-flexible-groups-enabled=true

I can confirm this error, tested with Besu latest 23.10.3 and 23.4.1 along with latest web3js-quorum
Getting Error -
Error: Returned error: Flexible Privacy group does not exist.

While with Besu 22.7.7 able to create Flexible group using web3js-quorum -

FIND Privacy Group Result:
{
  privacyGroupId: 'nFhwXEBPKym+r/8z2fYNBHIevpNABo/JVBtA4WShCgw=',

  ]
}

In Besu we have accpetance test for FlexiblePrivacyGroup which is passing for every run, and this uses web3j - https://github.com/hyperledger/besu/blob/main/acceptance-tests/tests/src/test/java/org/hyperledger/besu/tests/acceptance/privacy/FlexiblePrivacyAcceptanceTest.java

Now, we need to check if this regression is from Besu side or Web3js-quorum side.
