Issue
When creating a query pipeline with a specific Pipeline ID, Fusion displays an error stating that the pipeline already exists. However, the pipeline is not visible in the Fusion UI.
Diagnosis
This issue can occur if the query pipeline exists in the system but is not currently associated with any application. The pipeline will not appear in the Fusion UI’s application view until it is linked to an application.
Environment
Fusion 5.x and above, including Managed Fusion deployments.
Resolution
To associate an existing query pipeline with an application so that it appears in the UI:
Open the Fusion dashboard and select the target application.
Navigate to System > Object Explorer.
In the Object Explorer, select No Apps from the application filter.
Search for the missing query pipeline by its Pipeline ID.
Select the query pipeline from the results.
Click Add to this app to link the pipeline to the selected application.
Once the pipeline is associated with the application, it will appear in the Fusion UI under the application’s query pipelines list.
