[Twisted-Python] Twisted ( 17.1.0 ) exception

[Jacky Chuang (莊冠世)]

Hi,

            I use Buildbot ( 0.9.7 ) and Twisted (==17.1.0) to run git poller,

            Config is below.

       c['change_source'].append(changes.GitPoller(
        repourl='git at 172.23.45.81:/home/git/201701_postrack_swfw_app', branch='master',pollinterval=300, pollAtLaunch=True,
        gitbin="C:\\Program Files\\Git\\cmd\\git.exe",
        encoding="big5"))

       But it always to get the following exception :
      Can anybody tell what’s going wrong ? thanks!

      Jacky
