  Problem 1
    - Root composer.json requires zumba/json-serializer ~3.0.2, found zumba/json-serializer[3.0.2] but these were not loaded, because they are affected by security advisories ("PKSA-zhg7-9xn9-qv5j"). 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.
