Errors - Cognigy Documentation

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

All errors across services on the Overview tab.
Errors for a specific component by opening its corresponding tab.

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:

Open the Errors page. Click the error to see its details in the Error Details window.
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.
