Symfony\Flex\Cache::removeLegacyTags() must be of the type array,

[tjvdberg]

Hi guys,

Have an issue with updating my project. Composer.lock has symofny/flex version 1.0.80. Composer update results in: Updating symfony/flex (v1.0.80 => v1.0.85). All is ok.

When I do a Composer update subsequently I get a fatal error:

Fatal error: Uncaught TypeError: Argument 1 passed to Symfony\Flex\Cache::removeLegacyTags() must be of the type array, null given, called in _myprojectdir_/vendor/symfony/flex/src/Cache.php_ on line 85 and defined in _myprojectdir_/vendor/symfony/flex/src/Cache.php:91
