Hi all, I want to confirm that about the examples of the credential api that described at the following URL. http://docs.openstack.org/api/openstack-identity-service/3/content/create-credential-post-credentials.html I tried to request to our keystone server using the request example described in the reference. However we got a following error. {"error": {"message": "Invalid blob in credential", "code": 400, "title": "Bad Request"}} I think the reason of this error is because request is not using JSON string in "blob". Is my thinking correct? Has this problem been already registered? Do I need regist to BUG report if it not yet registered? Thank you.
