Error during kernel build Google Pixel 5

I am building a kernel for a google pixel 5 (first time, guides here have been a huge help!). **Getting to the issue:​** I'm trying out the following steps as they seem to be tailored to what I'm doing and using menuconfig cause lots of issues. https://groups.google.com/g/android-building/c/6HPwJloQkP8/m/oopcu67nAQAJ (response by Droid SMU with the step by step). Now, after running ./build_redbull.sh from the top directory, the following issue appears: INSTALL techpack/video/msm/msm-vidc.ko DEPMOD 4.19.135 ======================================================== Building external modules and installing them into staging directory + make -C private/msm-google-modules/wlan/qcacld-3.0 M=../msm-google-modules/wlan/qcacld-3.0 KERNEL_SRC=/local/home/bd/android/kernel/private/msm-google O=/local/home/bd/android/kernel/out/android-msm-pixel-4.19/private/msm-google CC=clang HOSTCC=clang LD=ld.lld HOSTLD=ld.lld HOSTLDFLAGS=-fuse-ld=lld NM=llvm-nm OBJCOPY=llvm-objcopy DEPMOD=depmod make: Entering directory '/local/home/bd/android/kernel/private/msm-google-modules/wlan/qcacld-3.0' make -C /local/home/bd/android/kernel/private/msm-google M=../msm-google-modules/wlan/qcacld-3.0 modules WLAN_ROOT=/local/home/bd/android/kernel/private/msm-google-modules/wlan/qcacld-3.0 MODNAME?=wlan CONFIG_QCA_WIFI_ISOC=0 CONFIG_QCA_WIFI_2_0=1 CONFIG_QCA_CLD_WLAN=m make: Entering directory '/local/home/bd/android/kernel/private/msm-google' make: Entering directory '/local/home/bd/android/kernel/out/android-msm-pixel-4.19/private/msm-google' /local/home/bd/android/kernel/private/msm-google/../msm-google-modules/wlan/qcacld-3.0/Kbuild:48: ../../../../../aosp_groups_version//local/home/bd/android/kernel/private/msm-google-modules/wlan/qcacld-3.0/configs/default_defconfig: No such file or directory make: *** No rule to make target '../../../../../aosp_groups_version//local/home/bd/android/kernel/private/msm-google-modules/wlan/qcacld-3.0/configs/default_defconfig'.

Or how would I go around trying to fix/debug a problem like this?
