VaultFS, not able to go deeper than one level in KV version2

[Adrián López]

When I try to access folders deeper than one level, it does not work.

sh-5.2$ VAULT_ADDR=http://localhost:8200 VAULT_TOKEN=XXX ls mnt/secret/admon
mnt/secret/admon
sh-5.2$ curl -H "X-Vault-Request: true" -H "X-Vault-Token: XXX" http://127.0.0.1:8200/v1/secret/metadata/admon?list=true
{"request_id":"11efcb4a-15b6-4583-6e8c-e39fd7925a49","lease_id":"","renewable":false,"lease_duration":0,"data":{"keys":["foobar"]},"wrap_info":null,"warnings":null,"auth":null}

Debug output:
