Error never happen on ESP32 Espressif System version 2.0.3 previously.

Also notice brown out detector library is missing in version 2.0.4 please include it in next release.

#include "soc/soc.h" //disable brownout problems
#include "soc/rtc_cntl_reg.h" //disable brownout problems
WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable brownout detector

// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
//            Ensure ESP32 Wrover Module or other board with PSRAM is selected
//            Partial images will be transmitted if image exceeds buffer size
//
//            You must select partition scheme from the board menu that has at least 3MB APP space.
//            Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15 
//            seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well

Let me know if this PR fixes this issue. Thanks.

I modified the "app_httpd.cpp" include file as per instructions and recompile with ESP32 Board Manager version 2.0.4 latest installed library with no compilation error. The problem have been resolved with your patch fix! Tested on Ai-Thinker ESP32-CAM board ESP32-S version.

Thank you very much for the solution! You may safely commit this fix to the master branch for global users to install the new fixed CameraWebServer example source code.

Thanks a million buddy! Cheers ;) Regards, Rodney Yeo @ http://rodyeo.dyndns.org
