Blender在导出为带动画的gltf (glb)文件时抛出关键帧错误- Key.path_resolve无法解决

Question

我是一个很新的搅拌器，动画和gltf。我已经成功地创建了我的3d模型，并能够将其导出为glb文件。目前，我正在尝试添加一个行走的动画，但导出到gltf的动画不起作用。这是导出器抛出的错误：

我认为gltf导出器找不到我的关键帧，但我不知道如何解决这个问题。任何帮助都是非常感谢的！谢谢

我已经为gltf导出器提交了一份bug报告。你可以在这里看到：https://github.com/KhronosGroup/glTF-Blender-IO/issues/1401删除无效的驱动程序解决了这个问题。
