The input data has to high precision. Round the data to 12 decimals
The thing is you have 3 points on a line with y coordinates.
19, 19.000000000000004 and 19
poly2tri will try to form a triangle and it will be degenerate. You will have
to round your data within epsilon 1e-12 and also make sure that no two points
get the same coordinate after the rounding.

I suggest you paste your data and triangulate with this app. when you get
errors. Might give you the reason of the triangulation failure.
