Bad Alias/connection name, SAML SSO Authentication failed.

Prior to the error message, the embedded browser which launches for SSO authentication displays a white page and hangs indefinitely.

The %TEMP%\Primavera.CacheService.log file contains the following exception:

Error Unhandled exception: System.NotImplementedException: Unable to cast to Microsoft.Web.WebView2.Core.Raw.ICoreWebView2Environment7. This may happen if you are using an interface not supported by the version of the WebView2 Runtime you are using.

 

EXPECTED BEHAVIOR:

P6 Professional code should execute a WebView2 minimal version check and fall back to IE controls if a supported version does not match the installed version.

The issue can be reproduced at will using the following steps:

  1. Install WebView2 v92.0.902.73.
  2. Attempt P6 Professional login configured for Cloud Connect / SSO.
