Problem With OpenAPI Private Identifiers

[dashty94]

Link to the code that reproduces this issue

https://codesandbox.io/p/sandbox/competent-swartz-l9zwsj

To Reproduce

1. Use [email protected] to generate typescript based on on OpenAPI specifications
2. Build the application (yarn build)
3. Start the production server (yarn start)
4. Open the application
5. Gets success responses of 200
6. The promise is not resolved in try and catch

Current vs. Expected behavior

The generated files work well when running the application locally with yarn dev. But when running the build, the requests do not get resolved. The only difference compared to the previous versions is that it uses private identifiers.

Downgrading to [email protected] resolves the issue and has no problem. The issue is with using the latest next versions (13.5.4).

Request example:

const getUser = async () => {
        try {
            const currentUser: any = await UsersSelfService.getSelf({}) // request is successfully made
           // But Does not reach here
        } catch (err) {
            // Does not reach here
        } 
    }

Seems to be a regression in #51943 (v13.4.8-canary.10), we will have a look, thanks!
