Description

I am using the openapi-cli tool to generate client code for typescript-nestjs application. But I have an issues with the typing of enums. They seem to be defined as string but the generated code types them as enum. Might not be a bug, but rather my lack of knowledge.

openapi-generator version

7.10.0

OpenAPI declaration file content or url

Link to file

geometry:
          type: object
          properties:
            type:
              type: string
              enum:
                - Point
                - Multipoint
                - Polygon

Generation Details

openapi-generator-cli generate -g typescript-nestjs -i assets/swagger.yml -o --skip-validate-spec

i had to use --skip-validate-spec, because there are some issues on the swagger definition. It's not mine it's a decleration file i got.

Steps to reproduce

use above commands to generate a client -> type of enum is declared as enum instead of string
