esp-idf: esp_ota_get_running_partition fail on OTA slot (IDFGH-1388)

Environment

-Development Kit: esp32 devkit v1 -Module or chip used: ESP32-WROOM-32 -IDF version: v3.2-130-g8e51f7e23 -Build System: Make -Compiler version: a1.22.0-80-g6c4433a -Operating System: Linux VM on Windows host -Power Supply: USB

Problem Description

When I call the function “esp_ota_get_running_partition” when running on an OTA slot (ota_0) I get an assertion failure and the program abort. When I call the same function on the factory partition I don’t have this problem.

It seems that the “esp_partition_find” function return an empty result while executing on an OTA slot.

Debug Logs
