The issue with the âExternal component has thrown an exceptionâ was solved by stopping UiRobot.exe task. Apparently, the previous version of the executable was running.
Hope itâll help!

Yes, it is working fine.The problem is while scheduling the workflow in the new v18.2.2 from task scheduler. Any help would be really appreciated. Thanks.
Hi @aashishgupta10@vishal.kumar
I think this is a bug in 2018.2, because older version works fine.
Similar issue is happen with HTTP Request activity also.
Now I found a workaround.
After published, it works fine.
