Some user information cannot be retrieved when using the REST API to retrieve group members

Hello,

We are using the Confluence Cloud REST API “Get group members” to retrieve group members, but when paging multiple times, some of the user information is always retrieved in duplicate. However, the number of group members retrieved as a whole is the same as the total number of group members, so as a result, some user information cannot be retrieved.

The target process is as follows.

Thank you,
