Hotpot (plugin)

Hi,

We updated the moodle version from 3.11.6 to 4.0.7 and now it shows the following error when trying to see the student report:

Exception - Argument 1 passed to core_user\fields::get_sql() must be of the type string, null given, called in [dirroot]/mod/taskchain/report/renderer.php on line 551
