The expression return $this->peek($lexer, Digia\GraphQL\Language\TokenKindEnum::SPREAD) ? $this->buildAST(Digia\GraphQL\Language\ASTBuilder\ASTKindEnum::FRAGMENT, $lexer) : $this->buildAST(Digia\GraphQL\Language\ASTBuilder\ASTKindEnum::FIELD, $lexer) could return the type null which is incompatible with the type-hinted return array. Consider adding an additional type-check to rule them out.

            ? $this->buildAST(ASTKindEnum::FRAGMENT, $lexer)
            : $this->buildAST(ASTKindEnum::FIELD, $lexer);
    }
