How do I coerce cookie from response.cookies to string I know the response.cookies is a table having another table as value but I just kept getting error bad argument #1 to pairs (table expected, got nil) when iterating through the table I need to be able to send cookie as a string I tried manipulating my code I don't seem to get it to work
