Validation error - Image must be set

Hi,
I am learning Uipath and at beginner level. Trying to create simple scripts. First time the script ran successfully, but later seeing validation error - Image must be set. How to Fix this ?

Thank You!

Can you share your workflow screenshot and error screenshot?

Thanks

Thank you Ksrinu, I was able to figure this issue out. Activity was executed without indicating the image on the screen, hence it throwed error - Image must be set. It’s working now.
