Hi，it looks you are testing with creating a new issue from APS Viewer with the cut planes are applied. Could you try with the code below? I believe you are using pushpinExtension. e.value.data is what comes from the event: pushpin.created of pushpinExtension. With this newIssue, use its position and viewState etc when calling POST Issues API.

 const newIssue = _this.pushPinExtension.getLegacyPushPinData
                      ? _this.pushPinExtension.getLegacyPushPinData(e.value)
                      : e.value.data;  

If this is not helpful and your scenario / code is different, please share the details on how you reproduced the problem.
