We are seeing in our Add Access JSON in the Duck Creek Claims - QA REST connection is sending duplicate calls resulting in duplicate entitlements being listed on the system
This error was caused by Multithreading instant provisioning being enabled at the same time as instant provisioning for connection type - REST only.
As per the setup, a multi-thread process was getting initiated which was creating duplicate provisioning actions.
Thus we added a new parameter ("createTriggerForInstantProvision") in the Configuration table.
This will enable an internal wsretry job to provision tasks and does not initiate multiple provisioning calls.
insert into configuration (NAME,Description,CONFIGDATA) values ('createTriggerForInstantProvision', 'createTriggerForInstantProvision','yes')
