90006: Invalid direction

This error means the request included an invalid direction value for a message. Valid Message resource directions are inbound, outbound-api, outbound-call, and outbound-reply.

• The request sent a direction value that is not one of the supported Message resource directions.
• The application or integration mapped the wrong value into the message direction field.

• Update the request or integration to use one of the supported values: inbound, outbound-api, outbound-call, or outbound-reply.
• Review the code that creates or updates the message and remove any unexpected direction value.
• If the request is already using a valid value and the error continues, contact Twilio Support.
