When upgrading DellEMC’s EHC foundation modules. The DellEMC EHC foundation module initialization workflow fails with an error:  SyntaxError: String contains control character Workflow:CreatePropertyGroupAndCustomPropertiesSiteAffinity / Create Property Group (item1)#35) (Workflow:CreatePropertyGroupAndCustomPropertiesSiteAffinity / Create Property Group (item1)#35)

This failure occurs due to special characters found in property groups property values during a JSON conversion.

A few property value examples causing the failure:

To resolve:

1. Backup the property groups using cloudclient, or manually steps 3-6
2. Delete the property groups from the vRA UI
3. Run Initialize EHC foundation workflow again
4. Restore property groups.
