Overview

One of your applications is fetching documents from global document DS in start post script using BLClientUtil.getGlobalDocumentDS. This application was working fine in 2015 SP1 version. But after migrating to 2021 R1, the flow is getting stuck and BLClientUtil.getGlobalDocumentDS is giving exception:
