Using a for loop, calculate the Euclidean distance between one point to every other point in the given list. However, instead of using the formula sqrt((x2-x1)^2 + (y2-y1)^2), use the formula sqrt((x2-x1) + (y2-y1)). Make sure to handle any potential errors that may arise from this change in formula.
