Generate routes error: Cannot use 'in' operator to search for 'xxx' in undefined

[Mathieu-Lala]

I am upgrading from node22 to node24 on my project, I am facing a type error in the routes generation.

The repo to reproduce the error: https://github.com/Mathieu-Lala/tsoa-issue-1862

I quickly tried with node25/26 and I have the same error as node24.

I have a different error with v7.0.0-alpha.0: This might be a complex generic type that needs special handling.
