Wrong Password / Unable to get volume! - I have the password

[sfrmattos]

I'm trying to open a raw disk dump (dd). I have the password, the image is working if I attach it on OSX.
Although I have used this tool several times in the past, this time I am getting the message that the password is wrong / Unable to get volume.
The FS is APFS for sure, no T2 encryption, BUT I read about the issues on converted HFS to APFS on upgrades. It may be the case.
I can read other volumes on the partition (Preboot, Recovery, VM and System), but I cant read the DATA volume, which I need to advance on a forensic / criminal case.

Any help will be appreciated.
