Error: failed to format output: consume [attachment] ...

[CapaBE]

(my goal is to retrieve the chat messages, not the media or attachments, can I decrypt this without the attachments to avoid the error below, since it seems to be related to attachments)

I failed to restore a Signal backup with this program:

OS: Win10
Version used: v0.1.7-alpha.2 (pre built binary)

Command used:
signal-back_windows_amd64 format -f XML -o backup-android.xml -P password.txt -v backupfile.backup
Then getting this error:
error: failed to format output: consume [attachment]: unable to process attachment: can't read attachment of length 0

Output file is generated but is empty

I also tried it with the latest version v0.1.6 and this is the result:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x0 pc=0x56c1f3]
