issue reproducible in AOT

[martincostello]

The stack trace suggests this is an issue in ASP.NET Core, rather than Swashbuckle - we're just calling into its API Description layer.

If it is an issue here, then we'll need a minimal reproducible example as a GitHub repository that demonstrates the issue you're experiencing so we can look into this further with the debugger. The example as-given is missing the endpoint method itself, as well as the project configuration (you mention native AoT, for example).
