25003: The provided user's last name is invalid

This error occurs when you create or update an organization-managed user through the SCIM API and the value in name.familyName is not accepted. Twilio creates users with the SCIM core user schema, and name.familyName is a supported field for both PUT and PATCH updates.

• Your POST /scim/v2/Users request includes an invalid value in name.familyName.
• Your PUT /scim/v2/Users/{id} request replaces the user record and includes an invalid value for name.familyName.
• Your PATCH /scim/v2/Users/{id} request uses path: "name.familyName" and supplies an invalid replacement value.

• Validate the value you send in name.familyName before submitting the request. If you are creating a user, format the request body as a valid SCIM core user object.
• If you are updating an existing user, change the last name only through the supported SCIM field name.familyName in a PUT or PATCH request.
• If you do not need to set a last name during user creation, omit the optional name object and send the required fields only, which are userName and emails.
