driver was not found

When I try to use a driver from the presenter list, such as from this URL:
https://api.d-id.com/clips/presenters/v2_public_alex@qcvo4gupoy/drivers,
and then use the following in the body of the POST request to https://api.d-id.com/clips:

"presenter_id": "v2_alex@qcvo4gupoy",
"driver_id": "e3nbserss8",

iI receive the following error response:
{
"kind": "NotFoundError",
"description": "driver was not found"
}

This problem occurs with all drivers from the presenter list. Can you help me resolve this issue?
