Cache data `from_meta` error, data type doesn't match

Hi, I faced with one error in caching data functions in the latest version

Traceback (most recent call last):
  File "/redacted/Karuha/karuha/event/base.py", line 17, in handler_runner
    ret = super(Event, event).call_handler(func)

pydantic_core._pydantic_core.ValidationError: 1 validation error for Subscription
  Input should be a valid dictionary [type=dict_type, input_value=b'{"comment":""}', input_type=bytes]

In karuha/data/meta.py line 228, we can solve it by changing

private=meta.private or None

to

private= json.loads(meta.private) if meta.private else None,

The other dict fields should also be changed.

This is indeed a bug. I declared the type of the public and trusted fields as Json, but forgot to change the type of the private field. I will submit a commit to fix this.

Now you can try the code on the dev branch to see if that solves the problem.

It works well now. Thanks for your immediate reply!
