/**

... other imports
import { HttpFile } from '../http/http';

The last import is wrong, do not exists.

Suggest a fix

Start with the reported openapi-generator-cli command using the typescript generator and --global-property models. Inspect the generated model output for the import { HttpFile } from '../http/http'; line and compare it with a models-only generation. Done means models-only output no longer contains the nonexistent http import.
