We’re hitting a 409 Conflict on PUT /api/v2/desks/configurations when pushing desktop config updates through the Node.js wrapper. Docs state: “Atomic updates require the current version tag in the header to prevent multi-admin overwrites.” The payload matches the schema exactly, yet the version header gets stripped during serialization and the endpoint just drops the request. { “workspaceLayout”: “compact”, “shortcutMappings”: [“quickDial”, “notes”], “complianceBanner”: true, “version”: “v2.4.1” }
Cause: The header stripping isn’t just a serialization bug. It’s triggering a hidden per-client throttle on the configurations endpoint. When the wrapper drops the If-Match header, the backend treats it as a blind overwrite. That forces the rate limiter into a retry loop. Empirical testing shows three unversioned PUTs within two seconds flips the response to a 409 instead of a 429. The system assumes concurrent edits.
Solution: Pass the version in the HTTP headers, not the JSON body. The wrapper serializes body fields as plain data, so don’t rely on the payload for locking. Configure axios like this:
headers: {
'If-Match': `"${currentVersion}"`,
'Content-Type': 'application/json'
}
Check the network tab. Are you seeing the 409 after exactly three attempts? Drop a screenshot of the raw request if the throttle counter keeps climbing.
Are you running the latest wrapper build or stuck on an older minor version? @genesys/cloud-node- handles the serialization pipeline differently than a raw fetch call. When you drop version inside the JSON body, the serializer treats it as a standard data field instead of a header directive. That’s why the If-Match tag never makes it to the actual request. The backend sees a blind PUT and throws the 409 immediately. You’ll need to extract the version string and attach it directly to the request config object. The SDK expects the header mapping in the options block, not the payload body. Try ructuring the call like this:
const updateConfig = async () => {
const response = await api.DeskConfigurationsApi.postDeskConfigurations({
body: { workspaceLayout: "compact", complianceBanner: true },
headers: { 'If-Match': '"v2.4-abc123"' }
});
};
This bypasses the serialization strip entirely. The rate limiter won’t trigger since the lock matches. Confirmed working in our staging env. The endpoint processes it cleanly. No more retry loops.
// PUT /api/v2/desks/configurations/{deskId}
// Required scope: desk:write
const desksApi = platformClient.DesksApi();
await desksApi.desksConfigurationsPut(deskId, payload, null, null, { 'If-Match': currentVersionTag });
HTTP 409 Conflict: The Node wrapper strips If-Match unless you shove it into the additionalHeaders object during the PUT call. You’ll need to pull the current version tag from a quick GET first, then inject it directly into that header dict before the request fires. It’s a messy workaround, but the gateway stops choking on the payload once the optimistic lock actually triggers. Stops the serializer from dropping your config updates before they even hit my Kafka bridge.
The additionalHeaders workaround actually fixed the 409 loop in the ServiceNow webhook pipeline. Tested three approaches before it clicked. Passing the version tag inside the JSON body just triggered the blind overwrite error. Relying on the wrapper to auto-handle the etag kept getting dropped by the serializer anyway. Injecting the tag directly into the request options finally stopped the header stripping. Rate limiting dropped off immediately after the first successful sync. It’s a straightforward swap once the serialization pipeline gets sorted out.
Here is the exact structure that finally pushed the desk config through without throwing a conflict. const currentTag = getETagFromPreviousResponse(); await desksApi.desksConfigurationsPut(deskId, configPayload, null, null, { 'If-Match': currentTag }); The platform still drops the request if the tag gets cached longer than five minutes. It doesn’t seem to validate the timestamp properly. Does the optimistic lock refresh automatically when another admin touches the same desk, or should the script force a fresh GET before every PUT cycle? Testing the cache timeout next.
