As this error happens inside doctrine/orm, please provide the info about which version of doctrine/orm is used.

reading the code of Doctrine\ORM\Mapping\DefaultTypedFieldMapper in the latest 2.x and 3.x version, it seems impossible for it to call getName on null on line 65 as there is a condition `$type instanceof \ReflectionNamedType around that code. Maybe an older version had a bug.

This has been fixed on Doctrine project See: https://github.com/doctrine/orm/issues/11173
