4.25.3 packaging for android fails. Android support does not exist

My project is failing to build after migrating to 4.25(Oculus version) from 4.23. The issue seems to be caused because androidX is enabled but jetifier isn’t successfully replacing all the android support references with their AndroidX counterparts. I went through the new android setup for 4.25 several times but I’m still unable to build.

errors:

In my case it was a “websocket” plugin I got from Github. The project has since been deleted. It had a UPL file which copied some files and enabled AndroidX (android.useAndroidX=true & android.enableJetifier=true) I commented out everything in that file and I managed to package successfully.
