Description

The import paths of models are broken when the option --modelSuffix is used.

// Generated e.g. with v6.2.1

import { InlineResponse200178MyTestApi } from '../model/inlineResponse200178MyTestApi'; // broken

But the file ../model/inlineResponse200178MyTestApi doesn't exists. The file name has no suffix.

//Generated with v7.0.0 (openapi-generator-cli-7.0.0-20221012.083708-4.jar)

import { InlineResponse200178MyTestApi } from '../model/inlineResponse200178'; // expected

Since you already fixed it in the new major version is there any chance that this bug could be fixed also in 6.x?

openapi-generator version

All versions >= 5.2 and < 7.0.0
