Broken pipe

[awenhu]

my code:

from flask import Flask, make_response, request
app = Flask(name)

@app.route("/dtu//", methods=["GET","OPTIONS"])
def dtu(dtuid, addr):
o = drawMultipleDtu(dtuid,addr)
resp = make_response(o)
resp.headers["Access-Control-Allow-Origin"] = "*"
resp.headers["Access-Control-Request-Method"] = "POST,GET,PUT,DELETE,OPTIONS"
resp.headers["Access-Control-Allow-Methods"] = "POST,GET,PUT,DELETE,OPTIONS"
resp.headers["Access-Control-Allow-Headers"] = "X-Requested-With,Content-Type"

if request.method == 'OPTIONS':
    print "it's OPTIONS"
return resp

app.run(host="0.0.0.0", port=5010)
I always got this error:

Exception happened during processing of request from ('192.168.44.1', 54412)
