Help with custom Gantt from Madison Giammaria

[TomHalpin]

Hi all!

I just came across an incredible looking Gantt from Madison Giammaria, built with the Deneb custom visualiser.

I have been trying to produce the core functionality using my own dataset but after countless attempts I am not able to produce the visual in Power BI. I have no idea what is causing this issue and I was hoping to leverage the expertise here.

Steps so far:

• Downloaded the Deneb visual and latest json code from the github repo.
• Mimicked the data, renamed my visual field names to match the expected value.
• Tried changing my table names directly to see if that helped.
• I have confirmed the data types and format match whats expected, by leveraging the example pbix provided.
• I even replicated the "root" row to see if that helped.

Expected view:

My current view:

 
The Log errors show:

[Error] Cannot read properties of undefined (reading 'enabled')

[Error] Cannot read properties of null (reading 'length')

As you can see nothing is generating within the visual itself, and I am completely lost to what the problem is.

I appreciate any and all help. I know this would be extemely powerful to use for my use cases and would like to get it working.

Thank you,

Tom

I found the issue. It was with my dataset. 
There were a couple empty dates which were causing some of my nodes on the hierarchy not to appear.

For anyone looking at this in the future, please ensure your entire tree is constructed properly.
