The constant Doctrine\ORM\Query\Lexer::T_IDENTIFIER was not found. Maybe you did not declare it correctly or list all dependencies?

It seems like $ormV2 ? Doctrine\ORM\Query\Lexer::T_DISTINCT : Doctrine\ORM\Query\TokenType::T_DISTINCT can also be of type Doctrine\ORM\Query\TokenType; however, parameter $type of Doctrine\Common\Lexer\AbstractLexer::isNextToken() does only seem to accept UnitEnum|integer|string, maybe add an additional type check?
