Anyone know why the Predictive Routing API throws a 422 Unprocessable Entity when I publish weekly schedules via the WFM v2 API? We are in America/Chicago and use the standard agent availability sync. The error points to conflicting shift swaps in the predictive queue configuration.
yaml
queue_config:
predictive_enabled: true
strategy: longest_available
adherence_threshold: 0.95
The payload validates locally but fails on the server. Is there a known latency issue between WFM publish and PR config sync?
This issue stems from the predictive routing engine rejecting schedules that violate the adherence threshold before the publish completes. when you set adherence_threshold to 0.95, the system validates that all scheduled agents meet that metric. if there are overlapping shift swaps or gaps in coverage, the api returns a 422 because the resulting capacity would drop below the required level for the ‘longest_available’ strategy.
try lowering the adherence_threshold temporarily to 0.85 during the publish phase. this allows the schedule to save without strict validation. once published, you can adjust the threshold back up if needed, but ensure the agent availability data is clean first. also check for any manual overrides in the wfm module that might conflict with the automated shifts. the error is not about the yaml syntax, but the data integrity of the schedule relative to the predictive rules. running a dry-run validation on the wfm side before hitting the api helps catch these conflicts early.
