Comment 13 for bug 1700766

Hello, sorry for late reply, I've been on vacation.

But, looks like last cherry-pick from Amy's branch broke that token caching you're talking about.
Here's my task JSON:

{
"SwiftObjects.create_object_then_download_object_and_delete_object" :[
{
  "runner": {
    "type": "constant",
    "concurrency": 5,
    "times": 10
  },
  "args": {
    "container_name": "interia-test",
    "object_size": 8192,
    "objects_per_container": 1000
  },
  "context": {
    "users": {
      "cache_tokens": True
    }
  }
}
]
}

Don't bother about that task name - it's a custom task created only to test whole CRUD chain at once, not for public use ATM.

But when I'm trying to run task with "cache_tokens": True, the schema validation fails:

Subtask SwiftObjects.create_object_then_download_object_and_delete_object[0] has wrong configuration
Subtask configuration:
{"runner": {"type": "constant", "concurrency": 5, "times": 10}, "args": {"container_name": "interia-test", "object_size": 8192, "objects_per_container": 1000}, "context": {"users": {"cache_tokens": true}}}

Reason(s):

                               'user_choice_method': {'$ref': '#/definitions/user_choice_method'}}}],
     'type': 'object'}

On instance:
    {"cache_tokens": true}`

Same thing with YAML input (in fact it's converted to JSON from what I know). But when I remove the cache_tokens option, and whole "users" section, it works well, but without caching.
