Unable to Use my RPA Unattended Bot

[Joatan Fontoura]

Hi, there!

I've started to learn RPA and I did a very simple flow (opens Windows calculator and do a math operation). It's working when I run using ServiceNow RPA Studio. Therefore, I published it to my instance (it's a PDI). It's a Unattended Bot Process. On the instance, I reference the package to a Bot Process and I referenced the Bot Process to a Robot and Credentials, just like it should be. My Bot Process is published and when I try to start it (from the instance to my Windows machine, using "Start Process" UI Action), it doesn't work. On the Process Job I see the message "Runtime plugins are downloading to the machine.". But I've tried a bunch of times and I receive always the same message.

You should know:

- Unattended Agent is running on the Windows machine and connect to the robot.

- My Windows account is an administrator.

- My Windows machine has full internet access and it's running Windows 11.

- My ServiceNow instance is Washington DC (Patch 3) and all RPA plugins are up-to-date.

The logs files from Unattended Robot Agent (Service and Runtime) are attached on this post. I was discussing with a coworker and he felt intrigued with a line on runtime file log:

<E AT="03-06-2024 05:08:04.320 " SYS="[T001:033|M147.21|FM3037.50|P6.41]" TYP="Info">Log file purging completed.</E>
<E AT="03-06-2024 05:08:04.320 " SYS="[T001:033|M147.21|FM3037.50|P6.41]" TYP="Exception">Unexpected exception occured.<Exception Position='0,0' methodName='Application_Startup' fileName=''><Message>Referência de objeto não definida para uma instância de um objeto.<Message><StackTrace> em UTL.RPA.ROBOT.Application.Application_Startup(Object sender, StartupEventArgs e)</StackTrace></Exception></E>

My Windows is n PT-BR but the message say something like "Object reference not set to an instance of an object."

And if you really want to help me and felt my problem interesting but need understand more about what I talked about, I recorded a video with the process fail (link is valid for 7 days): https://we.tl/t-H6KaQvrixm

I did another video recording how it's launching RPA Studio from my ServiceNow instance and running the process like a test (link is valid for 7 days): https://we.tl/t-P3Csm1Hyor

Thank you!

I realise by myself what was going on...

My Unattended Robot client version was obsolete. I was using 6.0 (and I downloaded it from my PDI last week!) and I realise that today, there was a new version: 8.0. I just installed it and my automation is working by Unattended Robot. I realised that my PDI receive a patch a couple days ago. Maybe ServiceNow changed the repository path with that update. I don't know. Anyway, it's working now. Lesson learned: always check if you are up-to-date even when you think you are.
