[nitpick] Using outdated GitHub Actions versions. actions/checkout@v4 and actions/setup-python@v4 are used, but as of January 2025, v5 versions exist. Consider updating to the latest stable versions for security and feature improvements.

app/config.py

+from pydantic import AnyUrl
+from pydantic_settings import BaseSettings


The ConfigDict import is missing from the app/config.py file. Line 18 uses ConfigDict as a class name, but it should either be importing ConfigDict from pydantic for the model_config attribute approach, or using Config as the inner class name. This is related to the Pydantic v2 migration issue.

app/middleware/validation.py

+                    # Re-create request with consumed body
+                    async def receive():
+                        return {"type": "http.request", "body": body}
+
+                    request._receive = receive
+


Direct assignment to request._receive is accessing a private attribute. This is fragile and may break with framework updates. Consider using Starlette's documented approach for request body handling, or wrapping the body in a proper streaming response. A better approach would be to store the body in request.state and use a custom dependency to retrieve it.

Suggested change

# Re-create request with consumed body

async def receive():

return {"type": "http.request", "body": body}

request._receive = receive

# Store the consumed body in request.state for downstream access

request.state.body = body

+            except:

+                pass


Bare except clause without exception type. This will catch all exceptions including KeyboardInterrupt and SystemExit, which can make debugging difficult. Consider catching specific exceptions like asyncio.TimeoutError or using except Exception:.
