# 61000: Add-ons: Internal server error

Log Level: ERROR

## Description

You see this error when Twilio hits an unexpected internal condition while processing an Add-on request. Twilio uses 61000 as a catch-all Add-ons error when the failure does not map to a more specific Add-ons code.

### Possible causes

* Twilio encountered an internal error while processing the Add-on request.
* The Add-on request failed in a way that did not match a more specific Add-ons error.
* Twilio could not complete Twilio-managed Add-ons processing for the request.

### Possible solutions

* Open the Twilio Debugger and review the error event and log properties for code 61000.
* Check the API response or callback for the failing Add-on request and capture the Request SID.
* Gather the Add-on unique name, Installed Add-on SID, and Add-on SID before you continue troubleshooting or contact support.
* Contact Twilio Support if the error continues or repeats. Twilio handles 61000 issues for Marketplace Listings.
