@matrixersp you're checking out of bounds on the array :-) maze[start[0]][start[1]] === 1 where either start[0] or start[1] is < 0 or > maze length

I have the same issue (JavaScript), all my tests pass and I'm checking if the move is out of bounds.

I've the same problem :(

Hi there. Your code is not checking if the move is out of bounds of the maze

Hi, just curious, but what exactly is the undefined object for which the property 3 cannot be read? (because this produces the error) I have not done this kata in JS, but it seems like you're trying to find the number 3 in something that can't or doesn't contain the numebr 3 . . . could that be the case?
