It may be that the file system of the output directory does not support certain operations, and the output directory does not use the fuse/sdcardfs file system.

I unpack vendor.img erofs in the ext4 file system. When unpacking it says:

Extract: Starting...
Extract: fs_config|file_contexts  saving...
Extract: fs_config|files_context  done.
Extract: [ 100.00% ]
Extract: An exception occurred while fetching, the info has been saved!
Extract: The operation took: 0.773 second(s)

and saved in a file. What are these exceptions?

Many images unpack normally, but some images have this situation. exception.log

Sorry, try again vendor.img

[sekaiacg]

I'm very sorry, I can't read data even with the erofs driver of the 6.1 kernel. This image file is not supported by the erofs driver or it uses an unopen source erofs driver.

But it does not rule out that the image file is damaged

that is, it is not possible to unpack it from the word at all? And so I wanted to get data from it, even without the rules of the file system ...

There are too many false images. After all, fsck.erofs does not understand them either. You can mount it, but there is simply no access to some files, nothing can be opened or copied.
