## [debug]无法获取发布任务状态，VSTS发布管理，回滚步骤 [英] ##[debug]Could not obtain release tasks status, VSTS Release Management, Rollback step
问题描述
我正在使用VSTS进行构建和发布管理，在发布定义中使用回滚步骤来回滚部署，如果任何步骤中断了发布定义。但是当我看到回滚步骤的调试日志时，它给出了错误"## [debug]可能
没有获得释放任务状态"并执行我的回滚Power Shell脚本，即使步骤成功或失败。
I am using VSTS for Build and Release management, in release definition using Rollback step to rollback the deployment if any of the step breaks from release definition. But when I see the debug logs for the Roll back step it is giving the error "##[debug]Could not obtain release tasks status" and executing my rollback Power Shell script even if the steps are successful or failed.
##[debug]Getting Personal Access Token for the Run
##[debug]Calling https://<myaccountname>.vsrm.visualstudio.com/<myteamprojectname>/_apis/release/releases/102/environments/167/tasks?api-version=2.1-preview.1 using obtained PAT token
##[debug]Could not obtain release tasks status
##[debug]The remote server returned an error: (500) Internal Server Error.
##[debug]Release Query unsuccessful.
##[debug]obtained task execution history as {}以下是我的脚本快照。
Below is my script snap.
