getting error while configuring wpa_spplicant in WPA3 SAE mode

Question

I configured as below in wpa_supplicant2.conf:

ctrl_interface=/var/run/wpa_supplicant 
ctrl_interface_group=0
sae_pwe=2
sae_groups=19 20 21 24 25
update_config=1
network={
    ssid=req_SSID
    proto=RSN
    key_mgmt=SAE 
    sae_pwe=2 
    pairwise=CCMP
    group=CCMP 
    ieee80211w=2 
    psk=PSD 
}

but while running this am getting following error

Successfully initialized wpa_supplicant
Line 8: invalid key_mgmt 'SAE'
Line 8: no key_mgmt values configured.
Line 8: failed to parse key_mgmt 'SAE'.
Line 14: failed to parse network block.

When you compile wpa_supplicant-2.10, make sure to set CONFIG_SAE=y:

wget https://w1.fi/releases/wpa_supplicant-2.10.tar.gz
tar -xvf wpa_supplicant-2.10.tar.gz
cd wpa_supplicant-2.10

cat > wpa_supplicant/.config << "EOF"
CONFIG_SAE=y
EOF

cd wpa_supplicant && make BINDIR=/usr/sbin LIBDIR=/usr/lib
