After upgrading to version 4.0, the Twilio SMS provider may fail to initialize if it still references the legacy 3.x class name.
In version 4.0, the internal package structure for message providers was updated. The class name for the Twilio SMS service must be updated in the configuration to ensure SMS delivery continues to function correctly.
3.x Class Name: com.broadcom.layer7authentication.mds.service.providers.sms.TwilioSmsService
4.0 Class Name: com.broadcom.layer7authentication.core.service.mds.providers.sms.TwilioSmsService
Product: IDSP
Release: 4.x and 3.x
To update the provider, you must issue a PATCH request to the Message Provider Management API. Twilio Attributes document sections describes this.
