💡 Hint

Common Mistakes

Using INFO level will show too many messages.

Using a format without level name hides severity.

Setting level=logging.ERROR ensures only error and above messages are shown. The format %(levelname)s: %(message)s shows the level and message.

5fill in blank

Fill all three blanks to log an error with exception info inside a FastAPI exception handler.

FastAPI

from fastapi import Request, HTTPException

@app.exception_handler(HTTPException)
async def http_exception_handler(request: Request, exc: HTTPException):
    app_logger.[1]('HTTP error occurred: %s', exc.detail, exc_info=[2])
    return JSONResponse(status_code=exc.status_code, content=[3])

Drag options to blanks, or click blank then click option'

Aerror

BTrue

C'error': exc.detail

D'message': exc.detail

💡 Hint

Common Mistakes

Using exc_info=False hides stack trace.

Using wrong keys in JSON response content.

Use error to log the error message. Setting exc_info=True includes the stack trace. The JSON response content should have a key like 'message' with the error detail.
