Code not generated for patternProperties in JSON Schemas about datamodel-code-generator HOT 7 OPEN

There might be other issues than the patternProperties.

from datamodel-code-generator.

The generator also fails to generate datamodels for the OpenAPI 3.1 JSON Schema.

Steps to reproduce:

#1 clone to get official JSON Schemas for OpenAPI Specification

git clone https://github.com/OAI/OpenAPI-Specification

#2 check that the JSON Schema is valid

check-jsonschema --verbose --schemafile "https://json-schema.org/draft/2020-12/schema" OpenAPI-Specification/schemas/v3.1/schema.json

 ok -- validation done
The following files were checked:
  OpenAPI-Specification/schemas/v3.1/schema.json

#3 run datamodel-codegen (fails)

datamodel-codegen --input-file-type jsonschema --input OpenAPI-Specification/schemas/v3.1/schema.json --output model.py

Error:

@koxudaxi With the risk of disturbing you, is there any other information needed?

If not, would you be able to confirm that this is a known issue or am I doing something wrong?
If it is a known issue, is this likely to be featured? How much work is it? Is it a good first issue?
