Several Settings in orgPreferenceSettings Cause 'ProblemDeployingSettings: Failed to deploy settings to scratch org' Error

[jty-reman]

I have been experimenting with changing from orgPreferences to settings in my Scratch definition file and I have discovered that the presence of any of these options causes an error when creating the scratch org:

"documentContentSearchEnabled": true,
"knowledgeEnabled": true,
"nameSuffixEnabled": true,
"middleNameEnabled": true
"liveAgentEnabled": true,
"chatterProfileEnabled": true

The other settings I am using that all do work fine are:
"chatterEnabled": true,
"enhancedEmailEnabled": true,
"networksEnabled": true,
"pathAssistantsEnabled": true,
"notesReservedPref01": true,

But, adding any of the first list (one at a time or in combination) causes the error with JSON output:
