Upload a hierarchy form with a branch is successful, but data not showing

[mirko77]

When I upload data for a project featuring a hierarchy and a branch, the upload is successful but data are not displayed on the server.

If I try to view the json I get

br />
<b>Fatal error</b>:  Uncaught exception 'ErrorException' with message 'Undefined index: Patient_key' in /var/www/html/plus/handlers/formHandler.php:165
Stack trace:
