Description

I have 2 classes, the first one (One1) has some fields and the second one (Two2) has also some fields and inherits the fields from class One1.

On my Java generator this works just fine.
On my Typescript-axios generator this doesnt work, and generate me the class One1, but the class Two2 doesnt have any inherits nor fields, it will do this:

export type Two2 = One1;

Ive also tried this on the Typescript-angular & Typescript-fetch generator, they also work just fine.
Only Typescript-Axios seems to have this issue.

openapi-generator version
