Describe the bug

I am experiencing a System.NullReferenceException error when attempting to set a value using the #!set magic command in a .NET Interactive notebook. The error occurs when I try to assign a URL value to a variable in the notebook environment. Below is the error message and stack trace provided:

Error: System.NullReferenceException: Object reference not set to an instance of an object.

The notebook content where the issue occurred is as follows:

#!meta

{"kernelInfo":{"defaultKernelName":"csharp","items":[{"aliases":[],"name":"csharp"}]}}

#!value

#!set --name url --value https://example.com/
