IIUC it seems like missing -d/--key-file option in front of 
"/etc/crypttab.key" string. Well it also depends on actual content of 
your /etc/crypttab.key file. Does it really contain backup of your 
keyslot passphrase (human readable text data)? Or does it contain volume 
key for your luks device (usually looks like binary data, bunch of 
random bytes that really should not be human readable:))
