Magisk not installing correctly - Unable to fully deploy modules (Requires Additional Setup)

[Whiskerc]

Description

I have a aosp build which I want to use magisk to install gapps (Using https://github.com/chickendrop89/systemless-gapps to build the app package)

On my base build without extendrom, I am able to install magisk, modify the boot.img and install my module fully. - apps & google play are installed.

I have added extendrom to my tree and build a new image, as far as I can see everything is built successfully, and after rebooting I see magisk.

However, every time I launch the app I see the 'Requires Additional Setup' message (I have seen the wiki that states that is normal once or twice, but for me it is every time the app launches. - even after additional reboots. I have tried updating with the direct install command, but get the Unsupported/Unkown image format message.

When I try to install my module, magisk performs the install, however after rebooting only some of the apps and services are there (google play store and apps dependent on it are missing)

Required(!) information

• custom OS name you build for (e.g. LOS, AXP.OS, ...) -> AOSP
• Android version (e.g. A9, A10, A11, ...) -> A13
• COMPLETE(!!!) output when executing: vendor/extendrom/er.sh -> er.sh output
• content of vendor/extendrom/Android.mk after running extendrom/a build -> Android.mk output

Here is also the output from patch.sh when it patches the boot img: patch.sh output
