13621: Invalid 'recordingStatusCallbackEvent'

Twilio returns this error when one or more values in recordingStatusCallbackEvent are invalid. Valid values are in-progress, completed, and absent. If you set recordingStatusCallback without recordingStatusCallbackEvent, Twilio sends completed by default.

• recordingStatusCallbackEvent includes a value other than in-progress, completed, or absent.
• Multiple callback events are separated with commas or another delimiter instead of spaces.

• Update recordingStatusCallbackEvent to use only supported values, separated by spaces, such as in-progress completed.
• Remove recordingStatusCallbackEvent if you only need the default completed callback.
