stax2aws versions 1.4.3 and older now deprecated
Stax has deprecated stax2aws versions 1.4.3 and older. These versions of the Stax Command Line Interface (CLI) utilized a device authorization grant solution which is no longer supported. Stax has removed the obsolete device flow resources from Stax-managed security accounts.
All users are required to upgrade to version 1.5.0 of stax2aws to continue using the Stax CLI.
If you have questions or concerns regarding the changes, please reach out by raising a support case.
