我有一个简单的 Flask API，其中一个端点调用另一个文件中的方法，以使用 request-html 从站点呈现一些 javascript

@app.route('/renderJavascript')
def get_attributes():
    return get_item_attributes('https://www.site.com.mx/site.html')

该方法的代码如下所示：

from requests_html import HTMLSession
from bs4 import BeautifulSoup

def get_item_attributes(url):
    #Connecting to site.
    session = HTMLSession()
    resp = session.get(url)
    resp.html.render()
    resp.session.close()
    soup = BeautifulSoup(resp.html.html,'lxml')

    ................................
    #Rest of the code is handling the data with bs4 and returning a json.

调用端点后，我收到此错误：
