Error 11750

Error - 11750

TwiML response body too large

In your response to Twilio's request, the response body is larger than 64 kB.

Possible Causes

  • The TwiML that you are serving is larger than 64 kB
  • You are serving non-TwiML content in your response

Possible Solutions

  • Verify that you are serving TwiML in your response to Twilio's request.
  • Verify that you are including this header in your TwiML response: <?xml version="1.0" encoding="UTF-8"?>
  • Limit your TwiML response to 64 kB or less.
  • Does your TwiML include the Play verb? Double-check the size of the MP3 file you include and ensure it is 64kb or less.
  • Check that your TwiML is formatted properly. To quickly verify your TwiML, you can copy and paste it into a new TwiML bin in the Twilio Console.
  • Check to see if your application is throwing errors. This may cause your application to send a large debug output as HTML back to Twilio instead of the expected TwiML.
  • If you are trying to send a 200 response in a status callback, use an empty TwiML response: <Response/>
