encode geometry

Nobody has claimed this yet.

Hi there, hope this is the right spot for my issue. If not apologize. Using mapbox-gl-direction api, input a route, get an array of coordinates and encode this result with polyline.js [https://github.com/mapbox/polyline](url) Get an encoded string, but the string is different from what I get when i use this mapbox example [https://docs.mapbox.com/help/demos/how-mapbox-works/how-directions-works.html](url).

Tried every polyline option to encode my coordinates, but never got the same result as the example shows in geometry.
Or can anybody let me know how to access the encoded string in geometry in the raw json object?

Thank you, and excuse my German-English.

Start by comparing the coordinate array from the mapbox-gl-direction API with the polyline.js output and the geometry shown in the Mapbox directions example. Check the raw JSON geometry to determine whether an encoded string is available; done means the encoding discrepancy or access path is clearly established.
