[SupertigerDev]

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the bug has not already been reported

Fastify version

5.0.0

Plugin version

9.0.1

Node.js version

21

Operating system

Linux

Operating system version (i.e. 20.04, 11.3, 10)

Ubuntu 20.04

Description

1. in postman, attach a large file
2. Post the request and then cancel it
3. See that the file is not deleted

Link to code that reproduces the bug

import Fastify from "fastify";
import multipart from "@fastify/multipart";
const fastify = Fastify({
  logger: true,
});
fastify.register(multipart, { logLevel: "error" });

fastify.post("/", async (request, reply) => {
  const files = await request.saveRequestFiles({
    limits: { files: 1, fields: 0, fileSize: 55655 * 1024 * 1024 },
  });

  reply.send({ test: "lol" });
});

fastify.listen({ port: 3000 });

edit: infact, it seems like saveRequestFiles promise just gets stuck forever or something

Expected Behavior

file should be deleted

Seems like the solution would be to add a catch block to pipeline and unlink the file
