Bug Description

When using version 6.12.0 of the platform-espressif32, the build process for an ESP-IDF framework project fails during the CMake configuration phase. It throws a Python AttributeError: 'NoneType' object has no attribute 'validation_alias' inside the idf_component_manager.

This issue does not occur with version 6.7.0 of the platform, which compiles successfully.

How to Reproduce

1. Create a new project with the following platformio.ini file, which specifies [email protected].

   [env:idf]
   platform = [email protected]
   board = esp32-pico-devkitm-2
   framework = espidf

2. Create a minimal src/main.cpp file. The content doesn't matter as the error happens before compilation.

   #include "freertos/FreeRTOS.h"
   #include "freertos/task.h"
   
   extern "C" void app_main(void)
   {
       while(1) {
           vTaskDelay(pdMS_TO_TICKS(1000));
       }
   }

3. Run the build command for the idf environment.

4. The build fails.

Actual Behavior

The build process fails with the following error log.

Expected Behavior

The project should successfully pass the CMake configuration phase and proceed to compile the source code, just as it does with [email protected].

Additional Context / Workaround

Workaround: The issue is resolved by pinning the platform version to a stable release, such as 6.11.0. The following platformio.ini configuration works perfectly.

[env:idf]
platform = [email protected]
board = esp32-pico-devkitm-2
framework = espidf
This strongly suggests the bug was introduced somewhere between version 6.11.0 and 6.12.0.
