This is related to when adding records in "subordinate cases" detail. I am getting error when client is calling this service "HierarchicalRecordSelectService" method "UpdateRecords". It is weird because this service exists on my configuration and this is Out of the box, we haven't done any customization into it. Any idea how to fix it?
In addition could you please contact our support at support@creatio.com directly and give us the reproducing steps with the external access if you can't handle this issue yourself and we will definitely investigate the problem.
