HerokuにPHP8.0のLaravelプロジェクトをデプロイしようとすると、次のようなエラーが発生しました。どうもPHP8.1として認識されているようです。

解決策
composer.jsonとcomposer.lockのphpバージョンを~8.0.0に変更します。
(composer.json)
"require": {
"php": "^7.2.5|~8.0.0",
"fideloper/proxy": "^4.4",
"laravel/framework": "^6.20.26",
"laravel/tinker": "^2.5",
"laravel/ui": "1.*"
},
(composer.lock)
"require": {
"php": "^7.2 || ~8.0.0"
},
PHPのバージョンを変更後、git push heroku mainを実行するとデプロイに成功しました。php (8.0.14)として認識されているのがわかります。

remote: ! Please remember to always keep your 'composer.lock' updated in
