使用“ buildbot sendchange”命令处理构建请求时出错

如何解决使用“ buildbot sendchange”命令处理构建请求时出错

我正在使用此命令开始构建：

buildbot sendchange --master=domain:9989 --who=tom --auth=username:'xxxxxxx' --branch=testing --project="apps/project-1" --category="apps"  --comment="push to build" application.yml tahani/tahani.model.py

该命令以以下错误开始构建：

exceptions.TypeError: unbound method _defaultCollapseRequestFn() must be called with Builder instance as first argument (got BuildMaster instance instead)

详细的回溯：
