Image uploaded to S3 cannot be displayed when run on Lambda

I'm trying to upload images to S3 via AWS Lambda using Hono, but when I open the image url it shows

The image cannot be displayed because it contains error

The image cannot be displayed because it contains error

My Setup:

Frontend: SvelteKit, sending a multipart/form-data request with the image.
Backend: AWS Lambda with Hono

Here's my route

routes.put("/:channelId", async (c: Context) => {
  const channelId = c.req.param("channelId");

  const formData = await c.req.formData();

  const updatedChannel = await ChannelService.updateChannel(
    channelId,
    formData
  );

  return c.json(updatedChannel, 200);
});

routes.put("/:channelId", async (c: Context) => {
  const channelId = c.req.param("channelId");

  const formData = await c.req.formData();

  const updatedChannel = await ChannelService.updateChannel(
    channelId,
    formData
  );

  return c.json(updatedChannel, 200);
});

routes.put("/:channelId", async (c: Context) => {
  const channelId = c.req.param("channelId");

  const formData = await c.req.formData();

  const updatedChannel = await ChannelService.updateChannel(
    channelId,
    formData
  );

  return c.json(updatedChannel, 200);
});

routes.put("/:channelId", async (c: Context) => {
  const channelId = c.req.param("channelId");

  const formData = await c.req.formData();

  const updatedChannel = await ChannelService.updateChannel(
    channelId,
    formData
  );

  return c.json(updatedChannel, 200);
});

The code for the uploading part is in the comment. It works perfectly fine on my local machine but once run on Lambda, the image is corrupted for whatever reason
