How to format start_date when using addTask

I have built a custom form to match branding and the form is working as expected. I have a date picker that also works. When I try to save the data , I try to set the task.start_date and it always fails when I do. I have tried several different formats and even matched the format of the task object but it doesn’t work and I get an error from a random function that I assume is trying to fix the date. I just can’t find the correct format to pass,

Any ideas??

Hello,
It is hard to imagine what happens in your case without an example. There are two ways to convert the date: from string to date object and vice versa. I think in your case you need something like that

var formatFunc = gantt.date.str_to_date("%d/%m/%Y"); task.start_date = formatFunc(date_from_the_picker);

If that doesn’t help you, I need to fully understand what happens in your case. Please send me a sample of your code to see what might be wrong. You can modify the following snippet:

After you edit the code and see that it reproduces the error, click on the “Share” button and copy the link for the snippet.

I just figured it out a few minutes ago. It seems that I was trying to pass a string object instead of a date object. I just modified the code to ensure it was passing a date object and that worked.

Thanks!!
