openHABian - Error500 after installation of "Map Transformation 2.0"

Facing this problem:

After having installed the MAP TRANSFORMATION
PaperUI reports an error500.

When I uninstall the MAP TRANSFORMATION the error500 is gone.

I just cannot find out where the problem is.
Anyone had this issue before me ?

I have the same problem

When I do a fresh installation of OH 2 and add Harmonyhub binding i can configure Harmony Things but when i install Map Transformation i receive error 500 in Paper UI when trying to configure Harmony Things.


This is a huge problem for me am am using many Map Transformations but when i install Map Transformation i can not configure my Harmony Things.
