Error Types in Ops Center

The error types are specific to each component. In Ops Center, you can view:

Errors from the past 7 days are displayed, including both run-time errors and those encountered in the Interaction Panel. To investigate a specific error:

  1. Open the Errors page. Click the error to see its details in the Error Details window.
  2. Click Go to <resource name>, for example, Go to Flow or Go to Endpoint, to open the page where the error occurred. Find the error by its code and follow the recommended steps to fix it.

List of Errors

Error Code Error Name Recommended Action
ERR_ENDPOINT_001 Endpoint Input Transformer Failed Check the Endpoint’s transformer settings, logs, and input mappings for errors.
ERR_ENDPOINT_002 Endpoint Output Transformer Failed Check the Endpoint’s transformer settings, logs, and output data format for errors.
ERR_ENDPOINT_003 Endpoint Execution Finished Transformer Failed Check the Endpoint’s transformer settings. Validate the final execution transformer logic. Ensure it properly handles the final payload and any cleanup logic.
ERR_ENDPOINT_004 Endpoint Inject Transformer Failed Check the Endpoint’s transformer settings. Check the injection logic that modifies request and response data. Ensure injected variables exist and are valid.
ERR_ENDPOINT_005 Endpoint Notify Transformer Failed Check the Endpoint’s transformer settings. Confirm that the notification transformer logic is implemented correctly. Validate event payloads and downstream subscribers.
ERR_FLOW_001 Flow Node Execution Failed Go to the Node and review its parameters. Use logs and the Interaction Panel to debug the Node.
ERR_FLOW_002 Flow Outbound HTTP Call Failed Check the outbound HTTP call settings: HTTP Request Node, endpoint URL, headers, auth, and payload. Test connectivity and response format.
ERR_FLOW_003 Flow NLU Intent Misconfigured Go to the Flow. Ensure the NLU Intent exists, is correctly configured, and trained. Retrain if needed.
ERR_FLOW_004 Flow NLU Embedding Model Misconfigured Go to the NLU embedding model in the Project settings and check that the model is correctly configured.
ERR_FLOW_005 Flow Generative AI Model Misconfigured Go to the model in the LLM configuration. Check the model is correctly configured, test its connection, verify API keys.
ERR_FLOW_006 Flow Knowledge AI Embedding Model Misconfigured Go to the embedding model in the LLM configuration. Check the model is correctly configured, test its connection, verify API keys. Ensure the Knowledge AI embedding model is deployed and accessible.
UNKNOWN The error occurs when Ops Center can’t determine the error type or identify which resource, such as LLM, Flow, NLU, or others, the issue occurred in. Use the information from the Message section in the Error Details window, then go to the Project to troubleshoot the issue.
