one platform returned an non-success response: %d

Error message

one platform returned an non-success response: %d

What it means

firelog's sendDataPoint POSTs the metric payload to the Firebase logging endpoint (firebaselogging-pa.googleapis.com). If the server responds with any status other than 200 OK, it returns "one platform returned an non-success response: %d" with the HTTP status code. The metric data point was not accepted by Google's logging backend.

Solutions

1. Check the reported status code: 4xx indicates payload/API-key problems; 5xx indicates retry later.
2. Verify network/proxy allows HTTPS to firebaselogging-pa.googleapis.com.
3. Disable skaffold metrics collection (`skaffold config set --global collect-metrics false`) — this error only affects telemetry, not skaffold functionality.
4. Retry later if the status is 429 or 5xx (server-side issue).

resp, err := http.Head("https://firebaselogging-pa.googleapis.com")
if err != nil {
    log.Println("firelog endpoint unreachable; telemetry will fail")
}

if err := sendDataPoint(dp); err != nil {
    var he *HTTPStatusError
    if strings.Contains(err.Error(), "non-success response") {
        // backoff and retry for 429/5xx only
    }
}

When it happens

Trigger: Metrics export attempts where the firelog POST returns a non-200 status — e.g. 400 from a malformed payload, 403/401 from API key rejection, or 429/5xx from server-side throttling/outages.

Common situations: Corporate proxies/firewalls intercepting the request, invalid or revoked firelog API key, Google-side service issues, or requests from blocked regions/networks.
