Does it happen with recent messages or with old one? With echo bot it works but may be because the message is in client cache...

The quick fix would be to fallback to usual message if you see 500 for POST /reply.

[ehussain]

This happens to normal message also. not only /reply end point.

Please fix it, it is happening with several instances now.

Hm, is it happening yet? There was huge update in web (whatsapp official one) and the engine, I see the issue is here for a year...
