Solution:
This error will occur when you map the "parentcustomerId" to CRM destination using text lookup but "parentCustomerId" field is customer dataType it contains both account and contact id. It will decide based on the "parentCustomerIdType" field.

In order to solve the issue we would need to map that field in the CRM destination
