Serial: This serial number is already registered on a different device
When you create devices from a CSV file, the import fails with a duplicate error if the same serial number is listed more than once in the uploaded CSV file, or if the same serial number is already used by a device that has been registered (created).
The identifier (Identifier) used for device management and the serial number that identifies the physical device must be one-to-one.
Check that the same serial number does not appear in the already registered device information or in the CSV file you are uploading.
