What is the reason this setting causes a 400 Bad Request when updating the NLU model via the Platform API in our multi-org Premium App? The endpoint PUT /api/v2/analytics/bots/nlu/models/{modelId} rejects the payload despite valid authentication. The confidenceThreshold field seems to be the culprit. Here is the configuration:
modelId: "en-us-bot-01"
confidenceThreshold: 0.75
language: "en-US"
Is there a hidden validation rule for threshold precision?
