oneOf items are not parsed recursively

Describe the bug Given the type Union[int, List[A], B]:

• A is treated as Any
• B class is generated empty with extra=allowed

To Reproduce

Example schema:

{"$schema":"http://json-schema.org/draft/2019-09/schema#", "oneOf":[{"type":"integer","$comment":"int"},{"type":"array","items":{"type":"object","properties":{"key":{"type":"object","properties":{"address":{"type":"string","$comment":"address"},"nat":{"type":"string","$comment":"nat"}},"required":["address","nat"],"additionalProperties":false,"$comment":"pair"},"value":{"type":"string","$comment":"nat"}},"required":["key","value"],"additionalProperties":false}}],"$comment":"big_map"}

Used commandline:

$ datamodel-codegen --input schema.json --output schema.py

Expected behavior All the oneOf sub-schemas are parsed recursively.

Version:

• OS: Ubuntu 18
• Python version: 3.9
• datamodel-code-generator version: 0.10.2
