Description
- When running a yield prediction task in Katalyst, the calculation fails and a server error is shown to the user.
- The server-side log contains an exception similar to:
com.acdlabs.spectrus_portal_common.shared.exceptions.BaseServerException: org.apache.http.client.ClientProtocolException - Other Katalyst functionality appears to work normally.
Solution to be handled by IT
- This error usually indicates that the Katalyst web server cannot successfully call the external yield‑prediction (machine learning) service over HTTP/HTTPS.
- Verify on the server side that:
- The configured yield‑prediction endpoint URL is correct and reachable from the Katalyst server.
- Required authentication (API keys, credentials) is valid and has not changed.
- Proxy or firewall rules are not blocking outbound connections from the Katalyst server to the ML service.
- After correcting the endpoint configuration or network routing, restart the Katalyst web application and re‑run the yield prediction. If the problem persists, enable detailed HTTP logging on the server and provide the logs to support for analysis.
