Cannot use ClerkMiddleware and input together

[Shivam-002]

I encountered following issue when using Clerk Middleware and jstack's input validation.

X [ERROR] [API Error] TypeError: This ReadableStream is disturbed (has already been read from), and cannot be used as a body.

at new ClerkRequest
(file:///E:/intonix/application-backup-v3/node_modules/@clerk/backend/src/tokens/clerkRequest.ts:29:5)

The main cause to the problem is clerk reading the stream after it's already been read.

When I debug it I found that this code trying to read it.

node_modules/wrangler/templates/middleware/middleware-ensure-req-body-drained.ts
var drainBody = /* @__PURE__ */ __name(async (request, env4, _ctx, middlewareCtx) => {
  try {
    return await middlewareCtx.next(request, env4);
  } finally {
    try {
      if (request.body !== null && !request.bodyUsed && request) {
        const reader = request.body.getReader();
        while (!(await reader.read()).done) {
        }
      }
    } catch (e) {
      console.error("Failed to drain the unused request body.", e);
    }
  }
}, "drainBody");
var middleware_ensure_req_body_drained_default = drainBody;

Just reporting the bug. As I am now directly using the await c.req.json() and manually parsing it. :)

Please lmk these things to help:

• jstack version
• which clerk middleware exactly youve used
• your middleware implementation you expect to work

thanks for raising the issue

Here is the middleware implementation.

const authMiddleware = j.middleware(async ({ c, next }) => {
  const { NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY, CLERK_SECRET_KEY } = env(c) as {
    NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY: string;
    CLERK_SECRET_KEY: string;
  };

  await honoClerkMiddleware({
    publishableKey: NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY,
    secretKey: CLERK_SECRET_KEY,
  })(c, async () => {
    const auth = getAuth(c);

    if (!auth?.userId) {
      c.json({ message: "You are not logged in." }, 401);
      return;
    }

    await next({ auth });
  });
});

When in a procedure i have input with a schema it throws this error. But as I remove the input and directly use the procedure it works. The error stack trace says it's clerk fault.
