To Reproduce Follow example here https://koxudaxi.github.io/datamodel-code-generator/jsonschema/ Example schema:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Person",
  "type": "object",
  "properties": {
    "firstName": {
      "type": "string",
      "description": "The person's first name."
    },
    "lastName": {
      "type": "string",
      "description": "The person's last name."
    },
    "age": {
      "description": "Age in years which must be equal to or greater than zero.",
      "type": "integer",
      "minimum": 0
    },
    "friends": {
      "type": "array"
    },
    "comment": {
      "type": "null"
    }
  }
}

Used commandline:

$ $ datamodel-codegen  --input person.json --input-file-type jsonschema --output model.py

Expected behavior Expected the model.py pydantic model to be generated

Version:

• OS: Windows 10
• Python version: 3.8.5
• datamodel-code-generator version: 0.11.12
• pydantic version: 1.5.1

@omgirok Thank you for creating this issue. I just reproduced the problem with pydantic 1.5.1. If I install pydnatic 1.8.1 then the error does not happen, I will fix it.
