    You trained a model packaged it with a custom Docker container for serving, and deployed it to Vertex AI Model Registry. When you submit a batch prediction job, it fails with this error: "Error model server never became ready. Please validate that your model file or container configuration are valid. " There are no additional errors in the logs. What should you do?

    • Add a logging configuration to your application to emit logs to Cloud Logging

    • Change the HTTP port in your model’s configuration to the default value of 8080

    • Change the healthRoute value in your model’s configuration to /healthcheck

    • Pull the Docker image locally, and use the docker run command to launch it locally. Use the docker logs command to explore the error logs
