Hi Goutham,
I tried running the CTK but encountered issues.
For partyManagement, I am unable to download the CTK[attaching the screenShot].
For accountManagement, I am facing the same issue and am unable to pass the CTK.
Could you please provide a reference input for RelatedParty in partyManagement and billCycleSpecification in accountManagement?

Thanks.

Hi Prajwal,
This should now be fixed on our side.
Could you please rerun the CTK tests for Party Management and Account Management and let us know if you're still seeing the same certification errors?
If anything persists, please share the latest CTK report her https://projects.tmforum.org/jira/servicedesk/customer/portal/3/create/278 and we'll investigate further.
Regards,
GB

Party Management Error

Post /individual and Post /organization
Payload used:
"relatedParty": [
{
"@type": "Party",
"role": "parent",
"partyOrPartyRole": {
"@type": "PartyRoleRef",
"id": "123456787654"
}
}
]
Account Management Error
