Control returns "Assess Denied" message only unattended
I am running a solution that enters data to a web app. There is one control that was tough to automate with. It is a button you click to upload a file. When I call onClick nothing happens. I've found only when I call mouseDown mouseUp and sendKeys enter key that it triggers the button.
This worked for development so far, but now that we're moving to unattended testing the button failing. When it gets to that part of the code tries the sendkeys method catches the error and returns "Access is denied" message.
Thank you.

@DanQuinlogThe FileUpload button must be triggered by a user action. This is why you need to use the mouse events or SendKeys to trigger it. When you are unattended, it would likely fail if your workstation where the bot is running is not unlocked.

@ThomasSasnett Do you think using this control unattended is a dead end then? Is the indicator that the control requires sendkeys to activate rather than a click?
Do you know any work around for this?

@DanQuinlog I have automated it in unattended bots before. It just requires that you make sure the machine (either physical or virtual) is unlocked. I have found that the easiest way is to use SendKeys, but in some cases, you need to do a positional mouse click to trigger it. Both of those will require the screen to be unlocked however.

@ThomasSasnettDo you know how I would unlock the screen when unattended? Is this something ootb in robot studio or a C# script?

@DanQuinlog If you use the RPA Service, it will unlock the workstation when it starts the bot. You would need to disable any sort of time-based locking that might occur as well. Your security team should know what those mechanisms are. I have used a script before to ensure a workstation does not lock, but I would avoid that and instead work with security to ensure your bots are allowed to be unlocked.

@ThomasSasnettWe're currently using the more basic Robot Manager setup. We manually start the bot, and it just listens for the activity call from pega to start work. From what you are saying, I understand that if we did the full Robot Runtime setup, where it would log into the machine and run the bot without user intervention, that it would be unlocked for the bot to run this automation?
If that is the case - we were scheduling to complete the robot manager setup, I'll just pass that we should do that sooner then later and it will fix the issue.
Does that sound like I understand it correctly?

@DanQuinlog If you configure the RPA Service, it will log in to the machine for you. The login will unlock the machine. Assuming you have ensured that the machine won't lock after a period of inactivity, then it will remain unlocked since runtime itself will not lock the machine.
