Unable to select drop down value from list

[PKS_09]

Hello there,

I am new to Power Automate Desktop. I was just wondering on what can be the reason i am sometimes unable to select the value from the drop-down list. 

The error i got is such as this :-

Microsoft.Flow.RPA.Desktop.Robin.SDK.ActionException: Failed to select option(s). ---> System.Exception: List doesn't contain option 'DDM Test'.

I recorded the steps through Web Recorder. Just last week the drop down list was functioning. But its not functioning now.

This happened before to other drop down list too. Is there a known bug for this? Also, how can i prevent this? Any suggestions is greatly welcomed. Thank you in advance! 🙂

Hello @PKS_09 

The error message says "List doesn't contain option 'DDM Test'", so I think that current HTML is different from when it was functioning.

Inspect HTML code of page content, and redefine your UI element selector, or input value of your variable for specifying option item.

Thank you.
