is being called with an argument that is not a class. This is a built-in Python function that checks if the first argument is a subclass of the second argument. It seems that the first argument provided is not a class, hence the TypeError.
This could be due to a variety of reasons. Perhaps there's a bug in the Prefect code, or maybe there's an issue with the environment in which it's running. It's also possible that the Prefect version you're using is incompatible with some other package in your environment.
I suggest checking the Prefect version you're using and ensuring it's compatible with your environment. If that doesn't help, you might want to reach out to the Prefect community or support for further assistance. They might have seen this issue before and could provide a solution.

function, which checks if a class is a subclass of another class. The error message is saying that the first argument to this function must be a class, but it's getting something else.
This error is occurring deep within the Prefect library, specifically in the pydantic
package, which is used for data validation. It seems to be having trouble with the Node
class in prefect.server.schemas.graph
.
I'm afraid I can't provide a solution without more context. It could be a bug in Prefect, a problem with your Python environment, or something else entirely. You might want to try updating Prefect and pydantic
to the latest versions, or reaching out to the Prefect community for help.
