19045: Invalid field type. Supported types: text, date, number

This error occurs when you send a custom field definition request with an unsupported field_type value. Supported custom field types are Text, Number, and Date.

• The request included a field_type value other than Text, Number, or Date.
• The request body for the Field Definitions endpoint did not use a valid field_type value from the supported enum.

• Update field_type to one of the supported values: Text, Number, or Date.
• Review the request body for the Field Definitions endpoint and resend the request with a valid name and field_type.
• If you create the field in the Twilio SendGrid console, choose one of the available field types when you add the custom field.

• Update Custom Field Definition
• Personalize and segment messages with custom fields
