Root Cause

Uploaded file size exceeds server's maximum request body size limit (default 1MB in Starlette).

generic

中文

上传的文件大小超过服务器的最大请求体大小限制（Starlette 默认 1MB）。

Workarounds

  1. 90% success 
    In Starlette, set max request size: app = Starlette(max_request_size=10*1024*1024) # 10MB
  2. 85% success 
    Use streaming upload: async def upload(request):
    async for chunk in request.stream():
        process(chunk)

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Application still enforces its own limit; must configure both.

  2. 80% fail

    Starlette reads entire body into memory before processing; limit applies first.
