What happened?

Hi, I am green in programming, however, I ensembled different libraries to make the ESP32CAM to video stream asynchronously using up to ver. 3.0.3 of ESP32 firmware by Espressif and version 3.3.12 of EspAsynWebServer (ESP32Async) using the Arduino IDE. Everything was fine until I used the latest version of 3.3.8 of ESP32 by Espressif and 3.10.3 of EspAsynWebServer (and also Async TCP). It raised a lots of problems.

Some solved issue is adding "const" in unit8_t AsyncServer::status() const in AsyncTCP.cpp and uint_t status() const: in AsyncTCP.h (suggested by Gemini AI - const mismatch between the newer AsyncTCP and ESPAsyncWebServer libraries)

Other problem found including "assert failed: tcp_alloc /IDF/components/lwip/lwip/src/core/tcp.c:1854 (Required to lock TCPIP core functionality!)" (LwIP requirement issue?) It was suggested to find out all the tcp_new() or tcp_alloc so as to be wrapped by LOCK_TCPIP_CORE() and UNLOCK_TCPIP_CORE(), but it seem many places inside the library involved and making me a mess ..., anyway it may out of my present skill ...

I wish to know wether the above issue was solved or has been solved in the latest version?

Minimal Reproductible Example (MRE)

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).

@Ray-25 please search before opening an issue.
You are not using the right Arduino version and/or the right versions of both async libs.

I am using latest ver. 3.0.3 of ESP32 firmware by Espressif and version 3.3.12 of EspAsynWebServer (ESP32Async) that was selected in the Arduino IDE.

Pretty sure you are not.
These issues are very old or comme when not using the right versions.
Also, if you use Arduino IDE, you are supposed to also know how its dumb library management system work. This IDE is very bad at dependency management so if you have troubles, save yourself some time and use a correct IDE like vscode with the pioarduino extension.
Otherwise if you still want to use Arduino IDE then make sure you know how to use it.
These issue come from a wrong IDE usage not the libs themselves.

Ok, its frustrating fact to an Arduino IDE user.
