The 05:30 JST state sync pipeline stalled on the messaging channel configuration. Terraform 1.9.8 paired with nice-cxone 1.20.3 throws a 409 Conflict when applying changes to the nice_cxone_digital_messaging_channel resource. The payload includes a standard WhatsApp business webhook URL and the channel type set to digital. Console output is doing jack all to help here. The provider successfully fetches the initial state, but the HTTP PUT request to /api/v2/digital/messaging/channels rejects the binding with a serialization mismatch error. State backup confirms zero drift across the last three runs. Rolled back to provider 1.19.9 just to test. Same 409 response. The platform API documentation mentions a required channel_status field, yet the provider schema marks it as computed. Manually patching the JSON body through Postman bypasses the conflict entirely. The Terraform apply step keeps freezing at the acd_routing_strategy block inside the messaging config. Logs show the request payload stripping the webhook_verification_token right before transmission. Tried forcing a state refresh with -refresh-only. It doesn’t change anything. The digital queue assignments remain detached after the run completes. Provider debug output points to a nested array mismatch in the routing_targets block. Nothing in the release notes addresses the webhook serialization change. Added a terraform plan -detailed-exitcode flag to capture the diff. The routing_targets array shows an unexpected null index at position two. The CXone UI displays the channel as active, but the backend API returns a 409 on any state mutation. Verified the API key permissions against the developer console. Full admin scope is granted. The provider still drops the token during serialization. Debug logs from the 05:30 run show the HTTP client timing out after 30 seconds on the PUT endpoint. State file remains locked until the timeout expires. Nothing in the provider changelog mentions the webhook_verification_token removal. The pipeline keeps retrying the same malformed request.
