Issue
Error 50056 indicate that a webhook response disabled processing of a command.
Product
Conversations Classic
Cause
This usually occurs when a webhook response to a webhook request from Twilio returns an HTTP status code other than 200 OK.
Resolution
Confirm the URL that processed the webhook request from Twilio, and check your logs for the endpoint to identify non-200 status responses.
In case you are using pre-event webhooks, please check if your endpoint is responding in less than 5 seconds.
Please reach out Twilio Support in case you require further assistance.
