Some code components are not showing dynamic value picker

Some code components of mine have properties not responding properly when launching the dynamic value window. It shows “undefined” instead of any data picker. Others don’t show this behavior at all. Is there a specific (code) attribute the Dynamic Value Window is looking for before showing the Data Picker or not? Thanks.

To Answer my own question, the issue was I had a conditional React Node Tree. That is, some child components where only shown on a condition. This was a big mistake. Although the components where visible on the Plasmic Studio Tree (left side panel), they weren’t included into the rendering tree and thus they didn’t have access to their parents’ provider data. Hence the ‘undefined’ value which meant: ‘undefined assertors’'. I just hope Plasmic would have given a more informative error message. Anyway, hope it helps someone else.
