25002: The provided user's first name is invalid

Twilio returns this error when the name.givenName value in a SCIM request for an organization-managed user is invalid. This can happen when you create a user with POST /scim/v2/Users or update a user with PUT /scim/v2/Users/{id} or PATCH /scim/v2/Users/{id}. The first name must be between 2 and 255 characters.

• The value sent in name.givenName is fewer than 2 characters.
• The value sent in name.givenName is longer than 255 characters.
• Your identity provider or SCIM client sent an invalid first-name value while provisioning or updating a managed user.
• A create request to POST /scim/v2/Users included an invalid name.givenName value.
• An update request to PUT /scim/v2/Users/{id} or PATCH /scim/v2/Users/{id} included an invalid name.givenName value.

• Update name.givenName so it contains between 2 and 255 characters before you send the request.
• Review the payload your SCIM client sends for POST /scim/v2/Users, PUT /scim/v2/Users/{id}, or PATCH /scim/v2/Users/{id} and correct the first-name value.
• If you provision users from an identity provider such as Okta, review your provisioning configuration so the first name sent to Twilio is valid.
• Send the request again after you correct the invalid first-name value.
• When you update a managed user, make sure any change to name.givenName uses a valid value.
