FIELD_CUSTOM_VALIDATION_EXCEPTION, To complete this action, ask your Salesforce admin to give you access to the required fields: AccountContactRelation.Contact

I installed Financial Could managed package in my Org. In one of the scenario when I'm updating Financial Account, I'm facing an issue mentioned below.  FIELD_CUSTOM_VALIDATION_EXCEPTION, To complete this action, ask your Salesforce admin to give you access to the required fields:  AccountContactRelation.Contact    In debug log, I can see that FinServ.FinancialAccountTrigger is executed and exception thrown inside this class.    Am I missing any custom permission or License assignment to the User ??
