Python flask mail api reported an error

from flask import Flask,request

    msg.html = html

    thr.start()

if __name__ == "__main__":
    app.run(host="0.0.0.0",debug=True)

Code as above, the function is to use flask mail api to send mail asynchronously. When you use curl call, you will report an error.
I don"t know why Thread reported an error. The module has been verified and there is no problem. Hope for advice

 curl http://127.0.0.1:5000/sendMail?title=11\&content="222"\&tolist=33@qq.com
