Swagger-codegen-maven-plugin with feign library build invalid paths - spring

Question

I have API.yaml file from supplier.
When codegen generates an API all my links are invalid because they have a question mark at the end
When i used openapi-generator-maven-plugin for this same API.yaml file, all links were correct.
I can't change swagger to openapi and feign library (project rules).
In project i'm using Feign 11.8 version and feign client has problem with question mark at the end (of course for requests without reqquest params)
How to fix it?
My plugin:
<plugin>

Generated api example:
#RequestLine("POST /api/something/FindSomething?")

})
SomethingsResponse findSomething(#Param("authorization") String authorization, SomethingRequest body);
