Old otacerts.zip not found in image

Hello,
I got the error "old otacerts.zip not found in image" when trying to use avbroot version 3.2.3.
I noticed you added "patching otacerts.zip" in version 3.0.0, so I tried using version 2.3.3 and it worked fine.
How should I handle this, or skip "patching otacerts.zip"?
Here is the link to the ota.zip used, and the log output of otaroot.

Thanks for reporting this. It's a known incompatibility. OnePlus stock ROMs put otacerts.zip in the my_engineering partition instead of the system partition and they set up AVB for that partition in an unusual way that makes it very complicated to patch.

If it helps at all, I can add a new option like --skip-otacerts-patch. I hadn't done that yet because there are so few OnePlus devices that properly support custom AVB keys nowadays. I assumed that nobody really used avbroot on OnePlus devices anymore.

I tried to modify the code to skip this, but after flash the avb_custom_key, recovery still can't start normally, which is exactly as same as #195. Thank you. I will downgrade the system version to see if it works when I'm free.
