When attempting to use a third party application such as Postman, we are following the instructions found inthios link Upload DNC Lists.  The problem is, the import works and shows the test numbers entered for a minute or so then the DNC list in the GUI shows a red exclimation point that says "import failed" when you hover over it.  We attempt to run a campaign that refernces the troubled DNC list and it works, meaning it does't dial the number and give us an ININ-OUTBOUND-ON-DNC-LIST.  Why is the list show import failed?  The only info we have when we run a GET /api/v2/outbound/dnclists/{dncListId}/importstatus is the following:

{
  "state": "FAILED",
  "totalRecords": 0,
  "completedRecords": 0,
  "percentComplete": 0,
  "failureReason": "NO_COLUMNS_DEFINED"
}

Hey Daniel,

You may want to reach out to the experts on the Genesys Cloud Developer Forum. It looks like someone else had an issue that was similar to yours, with the same error message.
