60393: Authenticator criteria are missing from the request

Twilio Verify could not create the Passkeys Factor because the authenticator criteria were missing. To create the passkey registration options, Verify needs authenticator_attachment, discoverable_credentials and user_verification. Verify takes them from the config object of the request or, when the request has no config, from the passkeys settings of the Verify Service.

The error message lists the missing fields.

• You created a Passkeys Factor without the config object, and the Verify Service does not have Passkeys.AuthenticatorAttachment, Passkeys.DiscoverableCredentials and Passkeys.UserVerification set.

• Send the config object when you create the Passkeys Factor, for example "config": {"authenticator_attachment": "platform", "discoverable_credentials": "preferred", "user_verification": "preferred"}.
• Set Passkeys.AuthenticatorAttachment, Passkeys.DiscoverableCredentials and Passkeys.UserVerification on the Verify Service, so you can create Passkeys Factors without config.

• Factor config invalid or not provided
