Error when using properties.{field} in plugin

hi, i need help

I created two plugins.

The first takes an array of data and returns me two lists. A text list and a number list. Until then all ok.

When I feed another plugin with these lists, when using the properties.{field} that receives any of the lists above, I get a TypeError error: Cannot read properties of null. However, I know that the lists are not empty.


fig. 1 - here is the list return by the first puglin.

fig 2 - here is the second plugin. I see de entry is not null.


fig 3 - this is the error

fig 4 - this is the code from the second.
