MissingMemberException

Dear Grasshoppers,

This is probably a very stupid question with a simple answer, yet I can't seem to solve it.

I would like to import a dataTree into my custom python object, but I appear to only get one member of the tree. Now I did some searching on the forum, and found several topics with exactly this problem.

I downloaded several examples and to my great suprise, these python blocks actually work! So I made again my own new python component, copied the code into it, and to my great suprise it doesn't work.

How is this possible and what am I doing wrong?

I humbly thank you for your time and effort.

Best regards,

Bart
