Exemption Request

This pull request contains only a spelling correction in an error message string literal. The change does not affect any functional
behavior, API surface, or CloudFormation output, therefore integration test changes are not necessary.

The fix corrects "lenght" to "length" in an error message, which is purely cosmetic and does not alter the logic or functionality of the
code.
