Master Data Integration Internal Server Error with Instance Creation Failed

[#1]

Hi
When I try to create an instance on BTP subaccount with plan, sap-integration I get Creation Failed with Internal Server Error.
It is for to sync with Subscription Billing.

I can create an instance on other subaccounts within the same Global account.

JSON is:

{

    "businessSystemId": "hrc-sub-bill-utilities",

    "enableTenantDeletion": true,

    "application": "hrc",

    "writePermissions": [{

            "entityType": "sap.odm.businesspartner.BusinessPartner"

        }, {

            "entityType": "sap.odm.product.Product"

        }, {

            "entityType": "sap.odm.finance.ExchangeRate"

        }

    ]

}

Any ideas? Appreciate any help.

Ger
