u need to check out of bound condition before trying to print

if(maze[sr][sc] == '0'){
    sol[sr][sc] = 1;
    printInaMaze(maze, sol, sr + 1, sc, er, ec);
    printInaMaze(maze, sol, sr, sc + 1, er, ec);
    sol[sr][sc] = 0;
}

add the is condition and add a return statement at the end of the function

updated code
