Issue with handleUpload #71

What happened?
I'm experiencing an issue with handling file uploads in the Async Web Server on ESP32. The handleUpload function is called only once and receives only the first chunk of data.
For small files (that fit within a single chunk), the upload works correctly. However, larger files that are sent in multiple chunks fail, as handleUpload is not called for subsequent parts.
When I use latest https://github.com/me-no-dev/ESPAsyncWebServer problem don't exists.
Stack Trace
Minimal Reproductible Example (MRE)
Board: ESP32-S3
void handleUpload(AsyncWebServerRequest *request, String filename, size_t index, uint8_t *data, size_t len, bool final) {
if (!index) {
Serial.printf("UploadStart: %s\n", filename.c_str());
}
if(len){
Serial.printf("Uploading %u B\n", len);
}
if (final) {
Serial.printf("UploadEnd: %s, %u B\n", filename.c_str(), index + len);
}
}
void serverConfig(){
server.on(
"/api/file", HTTP_POST,
[](AsyncWebServerRequest *request) {
request->send(200);
},
handleUpload);
server.begin();
Serial.println("Server init done!");
}
Log:
08:35:11.487 > UploadStart: sample-3s.mp3
08:35:11.508 > Uploading 1436 B
And this is all, no more chunks.
I confirm that:
- I have read the documentation.
- I have searched for similar discussions.
- I have searched for similar issues.
- I have looked at the examples.
- I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).
