Steps to reproduce

First, I used the API to add a new section to the parent-child sectioned document. Then, I used the API to add a child section to that section. After that, I used the API again to update the section. Finally, when I attempted to update the child section using the API once more, an error occurred.
The error message for updating the sub-section is as follows:

{
    "code": "not_found",
    "message": "Segment not found.",
    "status": 404
}

However, segmentation does exist in practice, as shown below:
