Uploading Snyk Graph failed with http code

Error message

Uploading Snyk Graph failed with http code {}: {}

What it means

GradleException thrown when the Snyk dependency-graph HTTP PUT returns any status other than HTTP 201 Created. The message includes the status code and the raw response body so the API's error text is surfaced.

Solutions

1. Read the response body in the message to see Snyk's specific error reason first.
2. Confirm the token is valid: rotate/re-check the Authorization header value for token.get().
3. Validate calculateEffectiveEndpoint() produces the correct Snyk API URL including the right org id.
4. If 429/5xx, retry with backoff or re-run the upload task later.

Example fix

// before
if (statusCode != HttpURLConnection.HTTP_CREATED) {
    throw new GradleException("Uploading Snyk Graph failed with http code " + statusCode + ": " + responseString);
}

// after - tolerate 200/201 and surface Snyk request id
if (statusCode != HttpURLConnection.HTTP_CREATED && statusCode != HttpURLConnection.HTTP_OK) {
    throw new GradleException("Uploading Snyk Graph failed with http code " + statusCode + ": " + responseString);
}

// Validate the token and endpoint shape before uploading
if (token.get() == null || token.get().isBlank()) {
    throw new GradleException("Snyk token not set; skipping upload");
}
String endpoint = calculateEffectiveEndpoint();
if (!endpoint.startsWith("https://")) {
    throw new GradleException("Snyk endpoint must be https: " + endpoint);
}

try {
    // upload logic
} catch (GradleException e) {
    if (e.getMessage().contains("failed with http code")) {
        getLogger().warn("Snyk upload rejected: {}", e.getMessage());
        // surface but do not fail the build if upload is best-effort
        return;
    }
    throw e;
}

When it happens

Trigger: client.execute(putRequest) returns a non-201 code: 401/403 for a bad or expired token, 404 for a wrong endpoint URL, 422 for a malformed payload, 429 for rate limiting, or 5xx for a Snyk-side outage.

Common situations: SNYK_TOKEN expired or revoked; organisation id omitted or wrong causing the ?org= query to resolve to a forbidden org; payload JSON schema drifted from Snyk API expectations; network proxy rewriting the response.
