How to use multiple buffers in gltf 2.0? - buffer

Question

I try to use multiple buffers to include different bin files(one for geometry data, one for animation data) but the animation bin file in buffers1 does not work in Babylonjs [Uncaught TypeError: Cannot read property 'frame' of undefined].
My questions are: Is there something wrong in my gltf file? How to use multiple bin file in gltf?
Below is my complete gltf file:
And the bin files
