Argument 'foo' was not set" after update to 4.1 in Cake Frosting #4374

^{Originally posted by pascalberger October 23, 2024}
Having the following code in a Cake Frosting project:

var value = context.Argument<string>("foo");

When running Cake with --foo=bar it worked in 4.0, but with 4.1 an Argument 'foo' was not set error is thrown.

See https://github.com/pascalberger/cake-4373 for a repro.
