3.0. We can't query the study unless it's already been deployed. To check whether this is the case, scroll all the way down to the bottom of the 'Edit Study' page, where you'll see a row of three buttons. If the study has been deployed, as is the case in our example, the left button labeled 'Deploy Study' will be grayed out and you will not be able to click on it. If, however, the study hasn't been deployed, the button will appear normally, and you can click on it to deploy the study.
The bottom of the 'Edit Study' page shows the 'Deploy Study' button (highlighted in red). In this example, the study has already been deployed so this button is grayed out. If your study hasn't yet been deployed, the button will appear normally, and you can click on it to deploy the study.
