I am using the REST API call...
https://api.miro.com/v2/orgs/{org_id}/teams/{team_id}/boards/{board_id}/data-classification
I am getting valid responses back from the call, but the vast majority of the time I am getting the following error returned even though the board has a classification label.
{
 "code": "internalError",
 "message": "Internal server error",
 "status": 500,
 "type": "error"
}
Thanks for the support!
