Fixes https://linear.app/chatwoot/issue/CW-6415/sending-large-attachments-11mb-via-telegram-channels-fails-with-http #### Issue Sending large attachments (~11MB) via Telegram channels fails with HTTP 502 (Bad Gateway) and 413 (Request Entity Too Large) errors. The issue is caused by HTTParty's built-in multipart encoding, which reads the entire file into an in-memory string before constructing the request body. For large files, this produces a malformed multipart request that Telegram's API proxy rejects. #### Solution Replace HTTParty with Faraday + multipart-post (both already available in the project) for the sendDocument multipart upload. The multipart-post gem streams file content directly from disk into the HTTP request, producing a correctly formed multipart body that Telegram accepts for large files. --------- Co-authored-by: Sojan Jose <sojan@pepalo.com>
