Marco - I have this same issue, and I have successfully completed the previous exercise of setting up the environment as an administrator. I first attempted this yesterday, using the Cloud Instance of the exercise system. When that didn't work, I downloaded the virtual environment and repeated all the setup steps, and got the same result. Since the StrategyDesigner@WhatIsInTheBox operator ID login failed, I logged in as administrator again and looked for this operator ID, and it did not exist. The only active "Strategy" related operators I found were StrategyDesigner@DecisionStrategyExecution and StrategyDesigner@dmorg. I could log in with those operator IDs, but I could not complete the exercise.
Please be aware, every Practicing what you learned lesson comes with an Environment Setup step. As part of this step the exercise system is configured for you so you can do the actual exercise. Like the operator you need to sign on to the system.
I don't understand where the miscommunication is here. I have repeatedly stated that I completed the environment setup step. Specifically I did these exact steps (below, as copied from the course material), and all completed without any errors being reported, yet I am still unable to login as StrategyDesigner@WhatIsInTheBox, nor can I find that OperatorID in the exercise system. Are you referring to a different environment setup step?
Exercise: Environment Setup
This exercise is to set-up the exercise system for the follow up exercises belonging to this lesson. You are asked to import a file containing the prerequisites.
It seems there is a miscommunication because you believe you imported C-746-EnvironmentSetup.zip and when I log into your cloud-based exercise system it turns out not to be the case, hence the operator is not available.
I was stuck on this for a few days. My browser was automatically unzipping the file C-746-EnvironmentSetup.zip , which I didn't realise so I couldn't import the actual file C-746-EnvironmentSetup.zip,. Instead I was incorrectly importing an item from the file. Thanks Marco
