General issue report

SDK Version: [ESP-IDF v5.1.2]
I'm currently working on an ESP32-S3 project that involves integrating ESP RainMaker and the Face Detection Web API from ESP-WHO. and the application binary size is approximately 1.95 MB. However, I've encountered a memory allocation issue that I'm struggling to resolve

Project Setup:
Microcontroller: ESP32-S3 WROOM2 with 32MB flash (custom PCB)
Software Components:
ESP RainMaker for IoT control and cloud integration
Face Detection Web API from ESP-WHO for image processing

I'm seeing errors like:

Questions:

What are the best practices for optimizing memory usage in an ESP32-S3 project that combines both ESP RainMaker and ESP-WHO?
Are there any specific configuration changes or code optimizations that could help reduce memory usage or prevent these allocation failures?
