Error: Duplicate schema names detected

[SamyZog]

Trying to generate swagger client from openapi 3.0.3
Orval v7.3.0 (also tried v7.2.0)

When generating i get an error

Error: Duplicate schema names detected:
  1x PatchedPayoutRequestListAdminDTOReimbursability
  1x PayoutRequestListAdminDTOReimbursability
  1x PayoutRequestRetrieveAdminDTOReimbursability
  1x PayoutRequestRetrieveUserDTOReimbursability
  1x PayoutRequestSetReimbursabilityDTOReimbursability

The schema is valid, I have ran it through the swagger editor and all is clean.

this is my config

export default defineConfig({
  newTechService: {
    hooks: {
      afterAllFilesWrite: "eslint --fix src/api",
    },
    output: {
      mode: "tags-split",
      target: "./src/api/query",
      schemas: "./src/api/model",
      client: "react-query",
      httpClient: "axios",
      urlEncodeParameters: false,
      clean: true,
      tslint: true,
      override: {
        fetch: {
          includeHttpResponseReturnType: false,
        },
        query: {
          signal: true,
          useInfinite: false,
        },
        mutator: {
          path: "./src/api/custom-instance/axios-instance.ts",
          name: "customInstance",
        },
        components: {
          schemas: {
            suffix: "DTO",
          },
          responses: {
            suffix: "Response",
          },
          parameters: {
            suffix: "Params",
          },
          requestBodies: {
            suffix: "Body",
          },
        },
      },
    },
    input: {
      target: ...
    },
  },
});

@SamyZog Could you provide the schema specification so I can try to replicate this?

@AllieJonsson This happens for me if i have a field name defined twice in both snake_case and camelCase on the same pydantic model class (later used in an endpoint).
