Exporting snippet in module breaks types if complex type is used

[AndreasHald]

Describe the bug

If you try to export a snippet from a module, but the snippet uses a complex type (something other than string | number) the code runs but you get a type error

(i'm unsure if this issue should be submitted to language tools, if so i apologize)
