Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires laravel/framework 8.*, found laravel/framework[v8.0.0, ..., v8.83.29] but these were not loaded, because they are affected by security advisories ("PKSA-8qx3-n5y5-vvnd", "PKSA-w7xr-vk7n-rstm", "PKSA-p3rx-dfwp-73ny", "PKSA-ckwp-rt7t-c46m", "PKSA-4npr-btr6-zhny", "PKSA-njrm-6dtg-m2pc", "PKSA-985r-hryy-555b"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add them to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config. Problem 2 - Root composer.json requires aws/aws-sdk-php ^3.216.1 -> satisfiable by aws/aws-sdk-php[3.368.0, ..., 3.370.1]. - aws/aws-sdk-php[3.368.0, ..., 3.370.1] require guzzlehttp/guzzle ^7.4.5 -> found guzzlehttp/guzzle[7.4.5, ..., 7.10.0] but it conflicts with your root composer.json require (6.*).
