Our state of the art Gantt chart


Post by jeanbaptiste.minani »

Dear Bryntum Support team,

This error is appearing on some projects only. We are on Gantt version 4.1.4.
Below is the sample dataset. We need your guidance on why it's happening and how to resolve it. Can Gantt be able to provide clear errors showing what's wrong in the datasets

Hey jeanbaptiste.minani,

Any reasons to not update to the latest version of Bryntum Suite? It's a very old version that you're using.

Besides that, we would need to see what your Gantt configuration looks like, to see if that is something missing there too.

Best regards,
Márcio

Ok. Let's upgrade to the latest version first. We will check if the error persists

Please let us know if that worked for you. We're here to help :)

Best regards,
Márcio

Upgrading to the latest version fixed the issue. But, it seems "startDate" is not being initialized. I will provide details in a separate thread.

Thanks
