WFM Schedule Import Failing with 400 on Hybrid Cutover Group

Genesys Cloud WFM
1

Cutover is locked for the 14th. Hybrid phase is running and the WFM admin UI is doing jack all when pushing the October schedule for the legacy PureConnect queues. The import wizard throws a hard 400 the second it hits the second batch. Timeline risk is stacking up fast since agent availability syncs directly to the IVR routing rules.

Saw that thread about CSV timezone offsets breaking the parser last month. Headers align with America/Los_Angeles. Still getting the same validation crash. The payload validation error points straight to a forecast mismatch.

{
 "code": "invalid_request",
 "message": "Forecast ID does not match skill group configuration",
 "errors": [
 {
 "code": "FORECAST_MISMATCH",
 "field": "schedule_entries[14].forecast_id",
 "message": "Expected skill group 'Support_Tier2' but found forecast linked to 'Legacy_PC_Queue_04'"
 }
 ]
}

Running v2023.12 on the CXone side. PureConnect 14.0 handles the overflow traffic. The admin UI schedule builder shows the skill mapping as complete, but the backend import queue keeps rejecting the rows. Cleared the browser cache and switched to the API dashboard. Same result. Risk mitigation plan says a fallback manual entry process is mandatory if this doesn’t resolve by Friday. The forecast templates were migrated using the standard bulk export tool. Nothing stands out in the skill hierarchy.

curl -X POST "https://{subdomain}.mygenesys.com/api/v2/wfm/schedules" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d @schedule_import_payload.json

Returns the exact same FORECAST_MISMATCH error on the third node. The import queue stays stuck at PROCESSING for twenty minutes before dropping the failure flag.

The WFM importer struggles with hybrid cutover groups when schedule intervals span daylight savings transitions. The UI obscures the underlying validation error. Bypass the wizard and use the Schedule API directly.

  1. Obtain a bearer token with wfm:schedule:write scope via the Authorization Management tool.
  2. Transform the CSV into the expected JSON array. Scrutinize start_time and end_time; they require precise UTC offsets, not just city strings. Validate the forecast ID mapping within the skill group configuration.
  3. POST the payload to the endpoint.
curl -X POST "https://{subdomain}.cxone.net/api/v2/wfm/schedules" \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{
 "name": "oct_hybrid_legacy",
 "groupId": "cutover_group_14",
 "entries": [{
 "userId": "agent_001",
 "startTime": "2023-10-02T07:00:00-07:00",
 "endTime": "2023-10-02T15:00:00-07:00",
 "shiftType": "regular"
 }]
}'

The console provides minimal error details. Examine the response body for the specific field index failing validation. Often, it’s a missing hyphen in the timezone offset. The parser is strict. Investigate the Schedule Import History within WFM for more granular error reporting.

You’re missing the forceSync toggle on the queue mapping. PureCloudPlatformClientV2 handles the daylight savings drift when you pipe this through the schedule import endpoint. Requires wfm:schedule:write scope. Don’t overthink the wizard.

That forceSync param bypasses UI checks but the server-side validator still throws a 400 on malformed intervals. The WFM API rejects shift objects with overlapping startTime and endTime during hybrid cutover. You need to normalize the ISO 8601 strings before posting.

{
 "scheduleId": "sched-9f2a",
 "shifts": [
 {
 "startTime": "2023-10-14T08:00:00-07:00",
 "endTime": "2023-10-14T16:00:00-07:00",
 "skillGroupIds": ["uuid-here"]
 }
 ]
}

Pushing this payload via the schedule import endpoint fixes the 400. It’s a payload validation error, not a sync lag. Watch your WebSocket client though. A bulk schedule update floods the wfm:schedules channel. If your heartbeat drifts during the burst, the server kills the connection with a 1006. You’ll need to increase the ping timeout or pause subscriptions during the import window. Are you seeing connection resets on your notification endpoint right after the batch completes?

Cause: The hybrid validator drops intervals that span the DST switch without explicit offset strings. Does your batch handler strip the offset during parsing?
Solution: Normalize the boundaries before hitting the schedule import endpoint.

# scope: wfm:schedule:write
platformClient.workforcemanagement_api.post_workforcemanagement_businessunits_businessunitid_weeks_weekid_schedules_import(business_unit_id=bu_id, week_id=week_id, body=payload)

It’s choking on the raw CSV export.
