Value cannot be null. Parameter name: password

I am trying out the Orchestrator tutorial Practice 3. When I run the robot from orchestrator, I am getting the alert Value cannot be null. Parameter name: password
How to handle if a user do not have a password?

Hi @jprabha

Welcome to the community :slight_smile:

I think what you are doing here, is trying to is creating a machine in the Orchestrator

For doing that, the orchestrator needs your domain and the password as well for the user you are creating the robot to run on

Hope this helps

Yes, that is right. User does not have a password.

Well I dont think its possible to use it without a password… This comes to the security concern as well…

I think the best way is to introduce a password for the user… it is the best approach to take


Had the same issue before as my windows PC doesn’t have any user/password.

To solve it, just go to your Robots, edit the one you will use, and at Password, below Domain\Username, type something, just don’t leave that blank - I’ve used “password”.
Afterwards it should work fine.


this worked for me as well :sweat_smile:
