Hello,
I am receiving a deployment error when trying to create a slice at the Amsterdam site. It appears there is a stale configuration or a resource collision on one of the data switches that is preventing the NSO commit from succeeding.
The orchestrator is trying to assign
HundredGigE0/0/0/9.2088, but the switch is rejecting it because it is already bound to an existing L2VPN.Error:
failed lease update- all units failed priming: Exception during create for unit: d254474c-833f-479c-9509-9027f953484c Playbook has failed tasks: NSO commit returned JSON-RPC error: type: rpc.method.failed, code: -32000, message: Method failed, data: message: External error in the NED implementation for device amst-data-sw: Wed Aug 19 08:22:36.180 UTCrnrn Failed to commit one or more configuration items during a pseudo-atomic operation.

Can you help me resolve this issue? (Slice-id: a63a1548-ac2c-406d-a7fc-1d1432287b51)
Thank you in advance for your assistance.
