Can't open json file output from DWPose Estimator

[ranknfyle]

In ComfyUI, I use "DWPose Estimator" node to detect a pose. I save its keypoints with the "Save Pose Keypoints" node. I want to load the post in "3D Pose Editor", but I get an error. Any idea how to fix this? I can code in Python, so if the json file needs to be changed, I can do it, but I need advice how. Thanks.
