36004: Error Retrieving File

Twilio returns this error when it cannot retrieve the Broadcast upload file from your request body. For Broadcast uploads, attach a GZIP-compressed JSON file as the value of the file key. Twilio APIs accept multipart/form-data for requests that include file content.

• The request body did not include a file key for the Broadcast upload.
• The uploaded file was sent under a different field name, so Twilio could not find the required file key.
• The request body format prevented Twilio from reading the uploaded file. Twilio APIs expect multipart/form-data or application/x-www-form-urlencoded, and file uploads should be sent in multipart/form-data.

• Send the upload as a .json.gz file and attach it as the value of the file key in the Broadcast Upload request body.
• Make sure the request uses multipart/form-data so the uploaded file is sent as a retrievable form part.
• If the request still fails, review the Error Logs or Messaging logs in Console to inspect the failing request and confirm which upload Twilio received.
