Simulate Key Strokes is not working in unattended mode.

in the 1st image I am clicking on search and then entering text in the 2nd image using simulate key stroke. Below is the code for the above logic

This is working when the VM is in presence but not able to enter the data in the 2nd image when the VM is not presence.

I tried all the ways to fix but nothing works out.

Please help me with the better approaches.
