cannot deep copy composite model #129

Open teubert opened 8 months ago

teubert commented 8 months ago

Describe the bug calling deep copy on a composite model returns an error

Relevant Requirements SWS requirements to switch over service to use progpy

To Reproduce create composite model deep copy

Expected behavior copy of composite model created
