Description

When generating client without 'withSeparateModelsAndApi' flag on, the generated client works with no problem. But when I set the withSeparateModelsAndApi to true and set the apiPackage and the modelPackage, application some how breaks. All I get is the error: 'SyntaxError: ambiguous indirect export: Address'.

This is how I use the API:

`
import { onMounted } from 'vue';
import { PetApi } from '@/api-axios/api/pet-api';
import { PetStatus } from '@/api-axios/models/';

const api = new PetApi();

const fetchPet = async () => {
try{
const response = await api.findPetsByStatus(PetStatus.Available);
console.log(response);
}
catch{

}
}

onMounted(() => {
fetchPet();
})
`

We also have problems with typescript-axios since 7.0.0 and withSeparateModelsAndApi=true. The previous version 6.6.0 was fine for us.

We have problems with generated models and allOf+discriminator types. With version 6.6.0 a MoreSpecialTypeAllOf.ts file was generated and exported as export GenericTyp & MoreSpecialTypeAllOf. Seems that inheritance is completly broken.
