Same problem, but different repo:
minimal-manifest-twrp/platform_manifest_twrp_omni#119
Have you been able to find any information? I have been trying to debug this for a while, but fruitlessly.

@Athwale
Hello there, It has been a while and i've asked about this particular problem on several repositories, As far as i know this only happens to mediatek processor and i theorize that it was due to proprietary blobs. I have so far not found any fixes for this and gave up

The easiest thing here would be if a twrp devel tried this out with the knowledge of how the internals work.
I suspect that the repositories maybe are broken and some files are missing. Maybe.
I found out that the variable in the Makefile that tells the builder to make a recovery image is not set to true. I do not know why though. If you set it to true manually, the compiler complains that it can not find some files.

Have you found out any options or environment variables that would produce more verbose output for debugging?
