Unable to parse schema Errors

Describe the bug
I'm attempting to convert a rather large open api schema to Pyhton bindings and am running across warnings that are dropping endpoints on the floor. I believe there is a couple of issues.

1. Refs not supported: Do you know if there are plans to add support for references in request body? I'll look at ways to flatten this schema out without references and try this again

"requestBody": {
                    "content": {
                        "application/json": {
                            "schema": {
                                "$ref": "#/components/schemas/MetadataFieldGroupType"
                            }
                        },
                        "application/xml": {
                            "schema": {
                                "$ref": "#/components/schemas/MetadataFieldGroupType"
                            }
                        }
                    },
                    "required": true,
                    "description": ""
                }

WARNING` parsing PUT /collection within collection. Endpoint will not be generated.
Could not find reference in parsed models or enums

Reference(ref='#/components/schemas/ItemSearchType')
WARNING parsing POST /collection within collection. Endpoint will not be generated.

Could not find reference in parsed models or enums
Reference(ref='#/components/schemas/CollectionType')

2. Parth parameters not match with path. I believe this may be due to the open "in path" vs "in query" issue.

WARNING parsing GET /collection/{collection-id}/item within collection. Endpoint will not be generated.

Incorrect path templating for /collection/{collection-id}/item (Path parameters do not match with path)

{
                        "required": true,
                        "schema": {
                            "type": "string"
                        },
                        "in": "path",
                        "name": "collection-id",
                        "description": "The collection id."
                    }

3. Generic cannot parse parameter of endpoint getAccessGraphDot

Schema(title=None, multipleOf=None, maximum=None, exclusiveMaximum=None, minimum=None, exclusiveMinimum=None, maxLength=None, minLength=None, pattern=None, maxItems=None, minItems=None, uniqueItems=None, maxProperties=None, minProperties=None, required=None, enum=['ancestor', 'grant'], type=<DataType.STRING: 'string'>, allOf=[], oneOf=[], anyOf=[], schema_not=None, items=None, properties=None, additionalProperties=None, description=None, schema_format=None, default=None, nullable=False, discriminator=None, readOnly=None, writeOnly=None, xml=None, externalDocs=None, example=None, deprecated=None)

To Reproduce
Steps to reproduce the behavior:

1. Run openapi-python-client generate --path openapi/spec.json
2. Run openapi-python-client generate --path openapi/spec.yaml

Expected behavior
A full python client should be generated without warnings.

OpenAPI Spec File
Standby. Making sure I have approval to share this schema since its coming from a 3rd party vendor.

Desktop (please complete the following information):

• OS: macOS 12.4
• Python Version: 3.8.9
• openapi-python-client version: 0.11.4

Bắt đầu với các lệnh openapi-python-client generate --path openapi/spec.json và .yaml, rồi xem lại các cảnh báo về tham chiếu request body, tham số path và getAccessGraphDot. Schema của vendor không được 포함, vì vậy hãy tái hiện khi schema khả dụng; được xem là hoàn tất khi toàn bộ Python client được tạo mà không có cảnh báo hoặc endpoint nào bị loại bỏ.
