Permission ticket endpoint giving 400

Question

I am working on sharing of resources using keycloak. Some time sharing is fine but in some cases its not working. When I checked the resources in admin Console. There are some request which are waiting to be accepted or deny. Until these request are not accepted manually the endpoint will keep giving 400 and the error"Permission Already Exist" my question is why these permissions are not working automatically as it is been given in some cases.

def _owner_action_scopes(owner_token, resource_id, scope, requester, granted):
    

    ticket_url = f"{server_internal_url}realms/{realm_name}/authz/protection/permission/ticket"
    
    data = {"resource": resource_id,
    "requester": requester,
    "granted": granted,
    "scopeName": scope}

    headers = {}

    headers["Content-Type"] = "application/json"
    headers["Authorization"] = f"Bearer {token}"
    headers["Host"] = kc_host
    status = requests.post(ticket_url, headers=headers, data=json.dumps(data), verify=VERIFY)

    return status
