Invalid API description for unbound functions

[t-bonk]

Hello,

in my CAP Java based service, I have defined the following CDS model:

db/db-model.cds:

entity TestEntity {
    key ID: String;
    name: String;
}

srv/test-service.cds:

using { TestEntity } from '../db/db-model';

service TestService {
  entity TestServiceEntity as projection on TestEntity;

  define type DataEntry {
    ID: String;
    name: String;
  }

  function getEntries(id: String not null, name: String not null) returns array of DataEntry;
}

When generating the openapi.json using this command:

cds compile srv/test-service.cds -2 openapi --openapi:url /odata/v4/TestService > openapi.json

I can see that the generated API description for the unbound function doesn't result in a conformant OData v4 URL. When using Swagger UI the following request URL is generated which is invalid:

http://localhost:8080/odata/v4/TestService/getEntries?id=%27k1%27&name=%27v1%27

The valid OData v4 request URL looks like this:

http://localhost:8080/odata/v4/TestService/getEntries(id=%27k1%27,name=%27v1%27)

This are the versions that are used in my project:

Hello @RoshniNaveenaS,

@RoshniNaveenaS BTW I also tested with version 1.0.7 which also has the issue.
