# 11750: TwiML response body too large

Log Type: APPLICATION

Log Level: ERROR

## Description

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; e.g. error message output

### 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](/docs/voice/twiml/play)? Double-check the encoding and MIME type to ensure they are supported.
* 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](https://www.twilio.com/console/runtime/twiml-bins/create).
* Check to see if your application is throwing errors. This may cause your application to send a large debug output 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/>`
