I Can't export a report using Restful api of Power Bi

[Anonymous]

Hi, I have been trying to use the ExportToFileInGroupAsync method in C #, it always returns Forbidden (403), and reading the error message tells me that it is not in a dedicated content

Request response:
Status: Forbidden (403)
Response: {"error": {"code": "InvalidRequest", "message": "Report requested for export is not on dedicated capacity"}}
RequestId: 6eb911d3-92c3-411b-b830-d7f2a334af6a

Any suggestion
Kind regards
