Hello,
After upgrading to 5.32.0 (upgraded from 5.31.0) server workflows fails to generate Arcgis server tokens. I've tried with two different installations, and different ArgGIS servers.

Here is the error:

   "traces": [
        "Error: 0: Unexpected Error: System.ArgumentException: Object of type 'System.Func`1[System.Object]' cannot be converted to type 'System.Func`1[System.Net.Http.HttpClient]'.",

      ]

  I rolled back to 5.31.0 and it's working again.

  Until this is addressed, do you know if it's possible to generate the token through a webrequest to the AGS server?

  You ought to be able to with Send Web Request. 

  Depending on your use case, you also might already have a token in your web map that you can grab; how you can access that token will be based on your application.  Get Layer could be useful if you're just trying to query a map layer, but if you need to run a server tool of some sort then you'll still need that token.
