Error when opening the gantt view from task:
TypeError: undefined is not an object (evaluating '_.min(group, function(element) {
return element.values[0].from;
}).values')

Can you provide me your task data?
Alternatively you can insert console.log(grouped); in line 156 and paste the results here.

Please find a dump of my task table.
task_data.txt
Edit:
I added console.log(grouped); on line 156 but I don't see the difference with or without it in the logs.
Anyway, here we go for the logs:

I mean the client-side javascript log.
the task table looks fine to me, though i cannot import SQL query results :)

The funny thing is that I switched to Chrome to get the javascript logs and it worked!
My problem appears to be only on Safari.
here is the logs from Safari console:
