[Plugin] help with mysql plugin error

The error log

Code:

cache_delete:?invalid?cache?id?'0'

This is my Pawn Code:

Code:

CMD:actorlist(playerid, params[])

{

new list[1024], skin, Float:AcX, Float:AcY, Float:AcZ, id, Descriptions[48];

new query[1024];

new Cache: actorlist;

mysql_format(SQLHandle, query, sizeof(query), "SELECT * FROM `actor`");

mysql_query(SQLHandle, query);

new rows = cache_num_rows();

if(rows)

{

format(list, sizeof(list), "ID\tSkin\tDescriptions\tDistance\n");

for(new i; i < rows; )

{

cache_get_value_name_int(i, "ID", id);

cache_get_value_name_int(i, "SkinID", skin);

cache_get_value_name_float(i,"X", AcX);

cache_get_value_name_float(i,"Y", AcY);

cache_get_value_name_float(i,"Z", AcZ);

cache_get_value_name(i,"Descriptions", Descriptions);

new Float: distance = GetPlayerDistanceFromPoint(playerid, AcX, AcY, AcZ);

format(list, sizeof(list), "%s%d\t%d\t%s\t%.2f\n", list, id, skin, Descriptions, distance);

}

ShowPlayerDialog(playerid, DIALOG_ACTOR_LIST, DIALOG_STYLE_TABLIST_HEADERS, "Actor List Manager", list, "Manage", "Close");

}

else

{

SendClientMessage(playerid, COLOR_GREY, "ERROR: There's no Actor list on server");

return 1;

}

cache_delete(actorlist);

return 1;

}

The system is works perfectly but why it's giving error?
