30115: Date format is incorrect

This error occurs when the Date field in your Messaging request does not use the required YYYY-MM-DD format. Twilio expects a calendar date only for this field.

• You included a timestamp, time, or timezone in the Date field instead of sending only a date.
• You used a two-digit year such as YY instead of a four-digit year such as YYYY.
• The value does not match the required YYYY-MM-DD pattern for the Date field.

• Send the Date field in YYYY-MM-DD format, for example 2023-08-13.
• Remove any time portion, timestamp, or timezone offset so the value contains only year, month, and day.
• Use a four-digit year and verify the full date is formatted correctly before you submit the request.
