I had a similar issue, triggered by this line

assert workflow_db.project == project_db

I had no problem with Pydantic v1, but upgrading to v2 I had to change the assertion like this

assert workflow_db.project.model_dump() == project_db.model_dump()

@ychiucco which file/path are you referring to here ?

[rgobbel]

The problem is that Collection.__init__ doesn't call super().__init__ soon enough. The Pydantic attributes don't exist until that call happens.
