With San Diego, custom contextual search topic blocks are not returning the desired results.DetailsWith San Diego, the custom contextual search topic blocks are not returning the desired result. The end-user might end up getting the error message as: "I'm having technical issues and won't be able to continue this conversation.There are no agents available at the moment. Please try again later."Additional InformationThe issue is mainly due to the 'vaSystem' variable that is being used in the VAGlobalContextualSearchUtil. After the upgrade to San Diego, it has been seen that the custom topic blocks that are using the VAGlobalContextualSearchUtil are in a scoped application, but it should be in the global scope as the variable vaSystem which is used in the can only be accessed in the 'global' scope. Up until Rome, the custom contextual search in a scoped application would work fine, even if VAGlobalContextualSearchUtil is called in a scoped topic block. As a result, after upgrade to SD, multiple customers might face this issue. Resolution:You need to create a clone of the custom contextual search topic block in the global application scope, and then use it in the global or scoped topics where the contextual search operation needs to be performed. This change has been introduced with the San Diego release.
