Description
Board
ESP32-S3 on custom PCB
Device Description
Described issue is device independant
Hardware Configuration
Independant
Version
v2.0.17
IDE Name
platformio
Operating System

PSRAM enabled
no
Upload speed
921600
Description
After several years of "works as expected" I now have crashes inside the Webserver.
(WebServer.h. "Now" means: Change from framework-arduinoespressif32 @ 3.20014 to framework-arduinoespressif32 @ 3.20017)
WbServer.h offers the method
void on(const Uri &uri, HTTPMethod method, THandlerFunction fn, THandlerFunction ufn); //ufn handles file uploads
to define two callbacks "Function" and "Uploads Function".
As said, until V 3.20014 everything worked as expected. From 3.20017 on, when exceuting a POST to the fn, THE UFN is called. NOT THE FN. (And my system then crashes because of wrong handling ...)
To demonstrate I provide:
- Demo-Program
- platformio.ini
- HTML Test-File
DEMO PROGRAM
(see below)
PLATFORMIO.INI
(I use a custom board file. Substitude it by an own board for ESP32-S3)
[platformio]
default_envs = esp32S3-with-6-10-0
[env]
framework = arduino
monitor_speed = 115200
upload_speed = 921600
monitor_filters = time, default
[env:esp32S3-with-6-10-0]
build_flags =
-D CORE_DEBUG_LEVEL=0
platform = espressif32@6.10.0
board = esp32s3_4MB_NOPSRAM_CDC
[env:esp32S3-with-6-6-0]
build_flags =
-D CORE_DEBUG_LEVEL=0
platform = espressif32@6.6.0

Why?
Can someone verify? Or provide a solution?
Thank you !
P.S.
There is a change in RequestHandlersImpl.h. in the class FunctionRequestHandler.
There appears two new methods canRaw and raw that do not exist in Version
3.20014. And they do something with the _ufn parameter. But I did not digg into deeper ...

Other Steps to Reproduce
0.) (Substitude SSID/PW in program for your needs!)
1.) Build the project with project environment esp32S3-with-6-6-0 (which comes with Version 2.14)
2.) Run and see the connected IP
3.) Substitude IP in HTML-File
4.) Open Brower and execute HTML-File
5.) See in PIO Terminal, that Function FN ist called
---> Works as expected
6.) Change to project environment esp32S3-with-6-10-0 (which comes with Version 2.17) and build
... rest the same as before
---> See in PIO Terminal, that Function UFN ist called. (... and than FN...?)
