missing config.json

[ekkis]

~/dev/signal-backup/Signal-Archive $ python3 ../scab.py 

Error: config.json not found in current directory!
Run again from inside your Signal Desktop user directory

the instructions here: https://matt.sh/signal-backup are incorrect. after the rsync I need to do cd Signal-Archive/Signal and then python3 ../../scab.py

but when I try that I get:

Traceback (most recent call last):
File "../../scab.py", line 41, in
c.execute("SELECT json, id, name, profileName, type, members FROM conversations")
pysqlcipher3.dbapi2.DatabaseError: file is not a database

the error does not provide the file name in question nor any additional information

I'm running on OSX 10.14.6 and have Signal 1.27.3 installed. help?
