Don't add any value for token_format under signing section


# Options defined in keystone

# Deprecated in favor of provider in the [token] section
# (string value)

The uuid token provider is deprecated in a future keystone, from this error i guess something wrong with your keystone.conf, could you paste the signing and token provider section in the keystone.conf for us to take a look?

[token] driver = keystone.token.backends.sql.Token

token e.g. kerberos, x509 (list value)
