Accessing a map property or key value always return null

[tard_gabriel]

Hi there,
Using
Neo4j 4.2.8
Browser 4.3.1
Apoc 4.2.0.4

Here is a simple query and the provided result.

Why in the return clause, I got only null if I'm trying to read entity.type?

I'm trying to create some data for the Keylines visualisation webkit.
