[BUG] BOM processing playbook: maximum recursion depth exceeded in comparison

[lpalovsky]

Describe the bug
Playbook playbook_03_bom_processing.yaml runs for hours and fails with error message

ERROR! Unexpected Exception, this is probably a bug: maximum recursion depth exceeded in comparison

This happens with any attempt to deploy Hana SR setup with NW instances on top.
Plain HanaSR (no SCS/ERS/PAS... ) works fine.

I am using slightly modified BOM file from examples repo called NW750SPS20_v0006ms

To reproduce
Steps to reproduce the behavior:

1. Prepare standard SDAF setup including deployment of at least SCS and PAS
2. Execute everything up to playbook playbook_03_bom_processing.yaml
3. Wait until process fails with mentioned error message

Expected behavior
Playbook finishes successfully

I'll send additional logs to @hdamecharla and @KimForss via mail as they can be lengthy.

Thank you for your help.
