The deferred execution request is not being processed

[butaikis]

I previously used this library from the old repository. I decided to upgrade, and after the upgrade, I started having errors when requesting my API. The fact is that the last request for which the error was delayed, I'll explain:

1. I received a request for ESP32
2. I am reading json, I have sent commands to a third-party UART module
3. I am waiting for a response
4. I am giving a response to the server

As far as I understand, as soon as I exit the handler
WebServer.on("/api", HTTP_POST, [this](AsyncWebServerRequest *request) {}, NULL, [this](AsyncWebServerRequest *request, uint8_t *data, size_t len, size_t index, size_t total){});
it immediately closes the connection, how to resolve this issue?
