Hello experts,

I am trying to create an element via HDL. I load the zip file and it is loaded with no issues: i get two green check marks. However, when I go to the element section, the element has a red cross for status: it is not created properly.

The content of the dat is in the code snippet. I have used the same template to create thousands of elements so I am very surprised. has anyone encountered a similar issue? If yes, what is the fix?
