Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires apereo/phpcas 1.3.8 (exact version match: 1.3.8 or 1.3.8.0), found apereo/phpcas[1.3.8] but these were not loaded, because they are affected by security advisories. To ignore the advisories, add ("PKSA-4b9f-kpvb-8rtq") 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 firebase/php-jwt 2.2.0 (exact version match: 2.2.0 or 2.2.0.0), found firebase/php-jwt[v2.2.0] but these were not loaded, because they are affected by security advisories. To ignore the advisories, add ("PKSA-2kqm-ps5x-s4f5") to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config.
