TRPC openapi API memory problem

[dawoodaijaz97]

Hi Everyone,
I am facing memory issues with trpc-openapi. I have a full-stack app in NextJS using TRPC. When I visit the /openapi route to visit the swagger documentation the server memory limit is reached and the server crashes. Please see the attached images.

Can someone please help me out with this? Thanks!

If I remove some routes from the app router. Then I do not get this problem.

export const appRouter = router({
    //asanaWebhook:AsanaWebhookRouter,
    channel: channelRouter,
    cloudmate: cloudmateRouter,
    //command:commandRouter,
    customField: customFieldRouter,
    //draft: draftRouter,
    email: EmailRouter,
    eventFilter:eventFilterRouter,
    //exception:exceptionRouter,
    // google: googleRouter,
    // microsoft: microsoftRouter,
    organization:organizationRouter,
    project: projectRouter,
    sms: SMSRouter,
    // task: taskRouter,
    // test: testRouter,
    user: userRouter,
    // worker:workerRouter,
    workspace: workspaceRouter,
});

export type AppRouter = typeof appRouter;

Is there a way I can paginate/lazy load the /api/openapi.json ?
