描述

If an http endpoint returns a redirect (for example http -> https upgrade), streaming client errors out:

HasClient @StreamBody
CallStack (from HasCallStack):
  error, called at src/Servant/Client/Core/Internal/HasClient.hs:550:44 in servant-client-core-0.15-KKVc3oxuLh47HhicA3CWtB:Servant.Client.Core.Internal.HasClient

研究方向
Investigate the handling of HTTP redirects in the streaming client code at servant client core/src/Servant/Client/Core/Internal/HasClient.hs line 550. Determine if the current error is a missing implementation or a bug. Look at related issues or PRs for redirect handling. Consider implementing redirect following for streaming requests or providing a clear error message.
