meta-writer --path /fotoalbum/0 "album" is working next level (meta-writer --path /fotoalbum/0/0 "2019") gives me an error

meta-writer --path /fotoalbum/0/0 "2019"

I saw this problem too. Make sure you use latest version? Otherwise there’s an extra forward slash somewhere in the code. Delete it? Also: try node index.js rather than meta-writer
