Root Cause

An unhandled exception occurred in the application code.

generic

中文

应用程序代码中发生了未处理的异常。

Workarounds

  1. 90% success Add exception handlers to log and return custom responses. 
    from starlette.responses import JSONResponse
@app.exception_handler(500)
async def internal_error(request, exc):
    return JSONResponse({'error': 'Internal server error'}, status_code=500)
  2. 85% success Use middleware to catch unhandled exceptions. 
    from starlette.middleware.base import BaseHTTPMiddleware
class ErrorHandlerMiddleware(BaseHTTPMiddleware):
    async def dispatch(self, request, call_next):
        try:
            response = await call_next(request)
        except Exception as e:
            return JSONResponse({'error': str(e)}, status_code=500)
        return response

Dead Ends

Common approaches that don't work:

  1. Using a bare except clause that hides the error. 60% fail

    Bare except catches all exceptions but doesn't log them, making debugging hard.

  2. Returning a string without proper error handling. 50% fail

    Returning a string doesn't prevent the 500 error; it only changes the response body.
