If, after upgrading the Niagara software on a Windows Supervisor, you get this error when you open the station in a browser: HTTP ERROR 500, Privileged Action
Exception, follow this procedure.
Prerequisites: You are connected to the Supervisor station and Workbench is open.
HTTPBasicScheme is the intended authenticator for use with the Web API protocol. Attempting to access a station using a browser
URL without this authentication scheme results in the privileged access exception error.
Perform the following steps:
Open the baja palette.
In the palette, expand AuthenticationSchemes > WebServicesSchemes and drag the HTTPBasicScheme authenticator component to the Config > Services > AuthenticationService > AuthenticationSchemes node in the Nav tree.
To create a new user or ensure that an existing user is configured for HTTPBasicScheme authentication, expand Config > Services > UserService, double-click the user name, select HTTPBasicScheme for Authentication Scheme Name and click Save.
Use an API platform, such as Postman to send an HTTP request to the Analytics Servlet to verify functionality. See the Niagara
Analytics Web API Protocol document for more details.
