Why does it say 'expected primary-expression before 'kolloba'''?

I am back to solving a question on Leetcode - https://leetcode.com/problems/minesweeper/description/. The question basically asks us to implement a mini-version of the minesweeper game (skipped since the exact details are not required).

With some online help from a Java code, I wrote the following code:

class Solution {
public:
    vector<vector<char>> updateBoard(vector<vector<char>>& board, vector<int>& click) {
        if(board.empty() || board[0].empty()) return vector<vector<char>>();

        int m=board.size(), n=board[0].size(), row=click[0], col=click[1];

        if(board[row][col]=='M') {
            board[row][col]='X';
            return board;
        }

        if(board[row][col]=='E') {
            int mineCounter=0;
            for(int i=-1; i<2; i++)
                for(int j=-1; j<2; j++) {
                    if(i==0 && j==0) continue;
                    int r=row+i, c=col+j;
                    if(r<0 || r>=m || c<0 || c>=n) continue;
                    if(board[r][c]=='M' || board[r][c]=='X') mineCounter++;
                }
            if(mineCounter) {
                board[row][col]=(char)mineCounter+'0';
                return board;
            } else {
                board[row][col]='B';
                for(int i=-1; i<2; i++)
                    for(int j=-1; j<2; j++) {
                        if(i==0 && j==0) continue;
                        int r=row+i, c=col+j;
                        if(r<0 || r>=m || c<0 ||c>=n) continue;
                        if(board[r][c]=='E') {
                            // vector<int> kolloba;
                            // kolloba.push_back(r);
                            // kolloba.push_back(c);
                            updateBoard(board, vector<int> kolloba={r, c});
                        }
                    }
            }
        }

        return board;
    }
};

I get the following compilation error:

Line 36: expected primary-expression before 'kolloba'

Ah, I know the other way to do this (as commented above); but I fail to understand the reason for compilation error in this particular case. Could someone please point out what am I doing wrong?

Note: Leetcode uses g++ 6.3 with the latest C++14 standard. So, although the above snippet is valid only in C++11; I don't think that is a problem; I feel I have done some really silly mistake. Could someone please point out?
