Unable to create periodic tokens

[F21]

I create a role that has token_period set.

vault write auth/oci/role/test \
    token_period = 1800 \
    token_policies = ["some_policy"]
    ocid_list = ["REDACTED"]

Logging in using the above role does not create a periodic/renewable token:

$ vault login -method=oci auth_type=instance role=test
Success! You are now authenticated. The token information displayed below
is already stored in the token helper. You do NOT need to run "vault login"
again. Future Vault requests will automatically use this token.
