4. Error is thrown as below: System.ArrayTypeMismatchException: Attempted to access an element as a type incompatible with the array.

Additional context
Sample code taken from https://github.com/microsoft/CopilotStudioSamples/blob/master/BotConnectorApp/BotConnectorApp/BotConnectorApp/Program.cs
Package version of Microsoft.Bot.Connector.DirectLine used is 3.0.2 (latest stable version)

Start with the referenced BotConnectorApp/Program.cs sample and the Microsoft.Bot.Connector.DirectLine 3.0.2 package, then reproduce the DirectLineClient(token) initialization using the token-generation URI described in the issue. Trace the reported System.ArrayTypeMismatchException in DirectLineClient.Initialize(); done means the client initializes without that exception.
