You are free to debug it and fix it? My tests were working. Maybe there will be a bug in special environment while sorting the chunks.

Did you find the solution? I have the same problem.
I'm using dropzone, $save->isFinished() returns false
nginx server

I think the problem may be when the request is with loadbalancer, the files generated in the chunk folder are different, the solution was to disable in the config the value of name->use all to false
'chunk' => [ // setup for the chunk naming setup to ensure same name upload at same time 'name' => [ 'use' => [ 'session' => false, // should the chunk name use the session id? The uploader must send cookie!, 'browser' => false, // instead of session we can use the ip and browser? ], ], ],

If the session changes then it is definitelly a problem :) Good find. Maybe default value should be session = false ?

Same issue. I have many logs with this problem. I use php 8.1.27, DropZone 5.9.3, Laravel 8.40. When the last chunk (for example, 5 out of 5) is uploaded, the file assembly begins, even if not all chunks have been uploaded yet (for example, 4 out of 5).

It is the condition of loading the last chunk that is checked here.

laravel-chunk-upload/src/Save/ChunkSave.php

Line 166 in cfbc429

protected function tryToBuildFullFileFromChunks()

laravel-chunk-upload/src/Handler/ChunksInRequestUploadHandler.php

Line 130 in cfbc429

public function isLastChunk()

I see the following error in the logs:

SplFileInfo::getType(): Lstat failed for /path/to/chunks/some-file-name.mp4-484aaeb2-4736-4340-a25c-bdf21b739e7f.10.part

Payload of the last request containing an error:

{
  "dzuuid": "62008064-10f1-4eed-b559-4bb02dcb5454",
  "dzchunkindex": "8",
  "dztotalfilesize": "122219582",
  "dzchunksize": "10000000",
  "dztotalchunkcount": "13",
  "dzchunkbyteoffset": "80000000",
  "_token": "********",
  "video": {
    "name": "some-file-name.mp4",
    "size": "0"
  }
}

idk how to solve this problem with code. This is the first time I've encountered chunks. Now I'm looking for the DropZone option to send the last chunk only after unloading all the others. Unsuccessfully

I will be grateful for any help 🙏

UPD: I found such a solution #91 (comment). It should work intuitively. I will write about the results – problem is still not solved

Maybe would be useful for someone. Here is my working example from frontend side.

  async addLarge ({ commit, state }, file) {
    const size = 1024 * 1000
    const chunks = Math.ceil(file.size / size)
    const chanked = []
    for (let i = 0; i < chunks; i++) {
      chanked.push(file.slice(
        i * size, Math.min(i * size + size, file.size), file.type
      ))
    }
    if (chanked.length === 0) {
      return
    }
    let i = 0
    const t = chanked.length
    while (chanked.length > 0) {
      const form = new FormData()
      form.append('chunk', i)
      form.append('chunks', t)
      form.append('file', chanked.shift(), file.name)
      await this.$axios.post(
        'YOUR_URL',
        form
      )
        .then((res) => {
          // Do something
        })
        .catch((e) => {
          console.error(e.response)
        })
      i++
    }
  },
