esp_wifi_config_80211_tx_rate not declared

[strakam]

Hello, I'm trying to flash the software to my ESP-32 cam. I followed the tutorial for ESP32 v4.3-beta1 and everything seems to work well.
However, after going to air_firmware and running idf.py -p /dev/ttyUSB0 flash monitor, I get this error:

../main/main.cpp:695:21: error: 'esp_wifi_config_80211_tx_rate' was not declared in this scope
     esp_err_t err = esp_wifi_config_80211_tx_rate(ESP_WIFI_IF, (wifi_phy_rate_t)rates[(int)value]);

I see that in main.cpp there are two other options for setting the esp_err_t. After trying the esp_wifi_internal_set_fix_rate, the program flashes successfully, but it doesn't seem to work. I'm gettin this error from the monitor:

Rebooting...

What might I have done wrong and how can I fix it? I'm working on Ubuntu 20.04 and using the v4.3-beta1 version of ESP-IDF.
Sorry if this problem comes from my lack of knowledge of these systems.
Thanks in advance

Hi, I'm facing the same problem. May I know the workaround for the issue please? I'm far from being an expert, so any help would be appreciated.
