It seems that the plugin ``/quad_pyblish_module/plugins/tvpaint/create/create_json.py``` is causing a problem, the Class declaration is not good which explains the error.

To remedy this, I've wrote a documentation which explains how to declare each kind of plugins and attributes you can use.

For this issue, you have to use :

from openpype.pipeline.create import Creator
class TVPaintJsonCreator(Creator):

instead of this :

from openpype.hosts.tvpaint.api.plugin import TVPaintAutoCreator
class TVPaintJsonCreator(TVPaintAutoCreator):

With the help of Creator(), you should also save some code with the help of create(self, subset_name, instance_data, pre_create_data) instead of create(self)

I let you check and let me know if you have some trouble with the quad-plugins repository.
