Hello XNAT team,

I have latest xnat and ohif viewer plugin, when I try to annotate image, the first measurement collection exported fine but when I click on a different scan and place another measurement and export then I get the error as below.

Thanks

upon checking the first annotation json and comparing it to the second annotation json, I found that the difference as below :

Annotation #1 json

"subject": {
"name": "70XXXXXXX986",
.....
}

Annotation #2 json

"subject": {
"name": {
"Alphabetic": " 70XXXXXXX986"
},
...
}

somehow the second annotation json is generating a deep nested Subject. I think this is might be the reason for parse issue, not sure how this could be fixed though.

Any help ?

Thanks
