Hey Guys I am trying to deploy my first prefect 3 flow using the

prefect.yaml

I followed the guide in the GitHub repo. But I keep getting this error

TypeError: No method for generating JsonSchema for core_schema.type='invalid' (expected: GenerateEmptySchemaForUserClasses.invalid_schema)

for reference here is my

prefect.yaml

content
