Unable to Upload Files Larger Than 100MB Using Hono Middleware.

[code-muni]

Hi Hono community,

I'm currently working on an application that requires uploading large video files using the Hono framework. Despite setting the bodyLimit middleware to accommodate files up to 500MB, I'm encountering issues where uploads larger than 100MB are failing.

In Thunder Client, I receive the following error message as a response:

Status: 413 Request Entity Too Large Size: 0 Bytes Time: 5 ms

However, I don't receive an error response in Thunder Client.

Here's a snippet of my current setup:

import { Hono } from "hono";
import { bodyLimit } from "@hono/middleware";

const app = new Hono();

const maxSize = 500 * 1024 * 1024; // 500MB

app.post(
  "/video",
  bodyLimit({
    maxSize,
    onError: (c) => {
      console.log("Upload exceeded maxSize of", maxSize);
      return c.text("File size exceeds the limit of 500MB", 413);
    },
  }),
  async (c) => {
    try {
      const { video } = await c.req.parseBody();

      if (video instanceof File) {
        console.log("File original name:", video.name);
        console.log("File type:", video.type);
        console.log("File size:", formatFileSize(video.size));
      } else {
        console.log("No video file found in the request.");
      }
    } catch (error) {
      console.error("Error parsing body:", error);
      return c.text("Error parsing file", 400);
    }
  },
);

app.onError((err, c) => {
  console.error("ERROR::- ", err);

  return c.json({
    status: "FAILED",
    message: "Internal Error",
    error: err.stack,
  });
});

function formatFileSize(bytes) {
  if (bytes < 1024) return `${bytes} B`;
  else if (bytes < 1024 * 1024) return `${(bytes / 1024).toFixed(2)} KB`;
  else if (bytes < 1024 * 1024 * 1024)
    return `${(bytes / (1024 * 1024)).toFixed(2)} MB`;
  else return `${(bytes / (1024 * 1024 * 1024)).toFixed(2)} GB`;
}

I have already increased the maxSize in the bodyLimit middleware to 500MB. Despite this, I'm still unable to upload files larger than 100MB. Are there any additional configurations or settings I need to adjust to support larger file uploads?

Any help or guidance would be greatly appreciated!

Thank you!

Hi @code-muni
I have 2 questions.

Could you tell me what runtime you use such as Deno, Node.js, wrangler and Bun?
And, have you tried to remove bodyLimit?
