please help what can i do for this error

Answer

According to the cheerio page, the correct way to load it is:

var $ = cheerio.load(body); // <-- note no .html()!

Calling .html() returns the body as an HTML string, which is likely not what you intended to do. Instead, just drop it to get the jQuery instance $.
