Org ID: 00Dbg000007XVPB (sandbox devAnis, refreshed from production 00D20000000CjigEAC).
Data Cloud was provisioned in this org on 2026-10-20. Data Cloud Setup Home shows "Your Data Cloud instance is live and connected to your home org" (1 data space, 7 connections).
Creating an Agentforce Data Library with Knowledge articles as its source (Article__kav, content field Contenu__c, data category filter) always fails at the first step, "Ingesting data into Data Cloud", with the message "Data Cloud asset provisioning failed. Please retry". We tried Retry and recreating the library: the error is the same.
The org contains Knowledge data streams copied from production during the sandbox refresh: Article_kav_Home, Article_DataCategorySelection_Home, DataCategory_Home and DataCategoryGroup_Home (created 2025-04-25). They are all in "Needs Activation" status and have never run. Their data lake objects already exist (for example Article_DataCategorySelection_Home__dll is ACTIVE), and Article_kav_Home is mapped in the default data space. The stream page offers no activation action, and clicking the refresh icon does not change the status. All 54 data streams in this org are in "Needs Activation".
We also tried to delete Article_kav_Home from the Data Streams list view ("Delete Data Stream"). The UI showed "Data Stream submitted for deletion", but 30 minutes later the stream (Id 1dsSZ0000000CkLYAU) and its data lake object Article_kav_Home__dll still exist, unchanged, and no error notification was received.
The user creating the library has the System Administrator profile and the Data Cloud Architect permission set. The Data Cloud Salesforce Connector permission set (sfdc_a360_sfcrm_data_extract) has read access to Article__kav and its fields.
Questions:
- How can we activate or remove these pre-existing Knowledge data streams, so that the Data Library can provision its own assets?
- Production also has Knowledge data streams. What procedure should we repeat in every sandbox refreshed from production?
