CRITICAL: Package stopped working after 3.1.1 update — "Class telesign\enterprise\sdk\Config not found" #8
Description
We experienced a critical production outage immediately after updating telesign/telesignenterprise from 3.1.0 to 3.1.1.

}
}
This error did not occur on 3.1.0, but immediately appeared after upgrading to 3.1.1.
The issue has caused a major disruption in our production environment.

Hey @tuktukvlad,
Thanks for reporting this — I'm a product manager at Telesign, and I wanted to jump in here.
Really sorry for the disruption this caused — totally understand how frustrating it is to hit a breaking issue after what should have been a safe patch update. The error came from the addition of a new Config class in 3.1.1, which is used by other parts of the SDK. While the class was properly added in the release, in some cases the autoloader may not correctly register it and the error occurred despite what should have been a non-breaking update. We’ll be reviewing our release process to avoid this in the future.
Quick workaround:
Thanks again for the clear report and for your patience. If you have any questions or need further assistance, please don’t hesitate to reach out.

Hey @LanaJ11,
Thanks for the prompt response and clarification.
We’ll try the suggested workaround with composer dump-autoload and monitor the results.
Appreciate your attention to the issue and efforts to improve the release process.
