Your PHP installation is too old. Refer to the Drupal PHP requirements for the currently recommended PHP version for this release. See PHP's version support documentation for more information on PHP's own support schedule.

Not that this matters much, but just for coverage this is my local

I used your Vanilla Drupal 9 recipe in the docs, and although I am on a non-supported version of docker, that doesn't appear to be the cause of issue here as an unsupported php version is being used by your recipe.

What does lando ssh -c "php -v" show?

[Stargate-project]

Stop using php 7.4 as the default for every PHP project. That is the problem. Php 8.1 should be the default.

[AaronFeledy]

The default should align with the product that you're running and the adoption level at hosting providers. The Drupal 9 recipe runs PHP 8.0 by default, which is supported by all versions of Drupal 9 and widely supported by hosting providers. Which version of Drupal are you running? Drupal 10 requires PHP 8.1, which is not installed by default on the Drupal 9 recipe.

Note that all the Drupal recipes should be on the relevant PHP versions, if anyone experiences otherwise, make sure your Lando is up-to-date (run lando update on 3.21+ versions).
