I am making an application using mainly Python to find the most fuel efficient route using primarily Google Maps data. I have been using the Encoded Polyline Algorithm to get elevation data, as well as a small Python module for the conversions. Normally, the conversion from LatLngs into polyline works fine. However, this URL returns a 400 error:

Using both the python module and `google.maps.geometry.encoding.decodePath()`

, the line has valid points in it (300 to be exact).

Any other line made like this works fine. **What makes this line in particular not work?**
