Not able to parse response for optimization or direction API for .geometries("geojson")

if I add .geometries("geojson") as routeOption in
https://github.com/mapbox/mapbox-java/blob/main/samples/src/main/java/com/mapbox/samples/BasicDirections.java
or
https://github.com/mapbox/mapbox-java/blob/main/samples/src/main/java/com/mapbox/samples/BasicOptimization.java

It throws an error
Expected a string but was BEGIN_OBJECT at line 1 column 412 path $.trips[0].geometry

Where as it works when we call via API playground or use polyline6 as geometry.

Caused by: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 412 path $.trips[0].geometry

I am using mapbox-sdk-core-6.3.0.jar

從 samples/src/main/java/com/mapbox/samples/BasicDirections.java 和 BasicOptimization.java 開始，使用 geometries("geojson") 重現此故障，並檢查 trips[0].geometry 中的回應。比較 GeoJSON 返回的物件與 polyline6 返回的字串；當 Directions 和 Optimization 回應都能在不出現 Gson 例外的情況下完成解析時，即表示完成。
