For Arize/Phoenix Cloud, the correct OTEL tracing endpoint is found in your Phoenix Cloud "Settings" page under the "Hostname" field. The endpoint should look like:
`https://app.phoenix.arize.com/s/<your-space> /v1/traces`
Replace `<your-space> ` with your actual space name. The endpoint you provided (`trace.phx.lovable.arize.com:443`) is not the standard Phoenix Cloud endpoint and may not work for trace ingestion. Make sure your API key is set as an HTTP header for authentication. If traces are not appearing, double-check the endpoint and API key configuration in your environment variables and code.
