Predictive Queue ICD Update Failing with 400 Bad Request and SDK AttributeError

Is the correct approach to use the POST /api/v2/queues/predictive endpoint when configuring the ICD threshold for a predictive routing strategy?

Apologies for the noob question, but I’m struggling with the SDK initialization and the API structure. The predictive bucket isn’t updating in the console.

I have a Python script that’s supposed to set the icd value to 120 seconds. The API keeps throwing a 400 Bad Request. The documentation mentions predictive_routing_settings, but I’m not sure if that’s a nested object or a separate resource. Confusing the terminology here. We’re running Genesys Cloud v23.7 in EU1.

Here’s the snippet. The console is doing jack all.

import gen_restapi

client = gen_restapi.PureCloudPlatformClientV2()
client.login_oauth_client_credentials("my_client_id", "my_secret")

# trying to set the predictive queue ICD
queue = client.queues_api.get_queue(queue_id="12345")
queue.predictive_bucket_settings.icd = 120
client.queues_api.put_queue(queue_id="12345", body=queue)

Error response:

{
 "code": "bad.request",
 "message": "The request body is invalid.",
 "details": "Field 'predictive_bucket_settings' is not recognized."
}

The logs show a timeout after 3 seconds. Also, the SDK version is 2.0.4.

Is predictive_bucket_settings the wrong key? I thought that’s how you adjust the predictive queue parameters. The error mentions routing_settings, but that’s for standard queues, right?

Traceback (most recent call last):
File “main.py”, line 15, in
client.queues_api.put_queue…
AttributeError: ‘Queue’ object has no attribute ‘predictive_bucket_settings’

The script crashes on the assignment line. My manager is asking why the predictive scores aren’t calculating. I think this config update is blocking it. The OAuth token looks valid because the GET request works fine. It’s only the PUT that fails. Also, I noticed the response headers have a retry-after but the status is 400. That seems odd. Maybe the SDK is serializing the object wrong? I tried passing a dict instead of the object, but got the same error. The incomplete log below shows the request headers. Authorization: Bearer eyJ... [cut]. The payload size is small. Not a timeout issue. Just a schema mismatch. I really apologize for the basic question. I’ve checked the swagger docs. The Queue model doesn’t list predictive_bucket_settings. It lists routing_settings. But routing_settings has a predictive field? I’m getting tangled up. The Python SDK models might be outdated. I’m on the latest pip install. gen-restapi==2.0.4. The error says predictive_bucket_settings is not recognized. Maybe I need to use routing_settings.predictive.icd? I tried that and got a 500 Internal Server Error. I can’t find any examples in the community posts for this specific flow.

The official REST specification requires the POST /api/v2/queues/predictive endpoint to receive a JSON array, not a single object. PureCloudPlatformClientV2 expects the payload wrapped in a list, otherwise the validation layer throws a 400. We tried sending the raw dictionary first. That failed with a missing queueId error. We added the scope queue:edit next. The request still dropped. PureCloudPlatformClientV2 actually strips nested nulls before serialization, so the icd field gets omitted entirely.

[{ "queueId": "your-queue-uuid", "predictiveQueue": { "icd": 120 } }]

You’ll want to push this exact structure through a Studio REST Proxy SNIPPET action to bypass the Python serialization bug. Have you checked the network tab to see if the header is actually hitting application/json? The timeout usually happens right after the hash calculation.

Cause: It’s a total mess when the ADMIN UI completely ignores the request if the PREDICTIVE CONFIGURATION isn’t pre-enabled. Solution: Wrap the payload in a list and attach the QUEUE:EDIT SCOPE before firing the call, otherwise the validation layer just drops it.

from purecloudplatformclientv2 import PlatformApiClient
client = PlatformApiClient('https://api.mypurecloud.com')
payload = [{"queueId": "your-queue-id", "icd": 120}]
client.queues_api.post_queues_predictive(body=payload)

Check the QUEUE ANALYTICS dashboard.

Wrap that payload in a list and toss in the queue:edit scope before firing it off. In CIC we used to hit the exact same validation wall when pushing thresholds via ICWS, so you’ll see the chokes without the array wrapper.
