API: getProjectSetting throws {"code":108, "message":"Internal error: Unknown setting key"}} Follow

Attempting to call getProjectSetting with the following params based off GetProjectSettingRequestDTO:

{"projectId": "sample-project", "request": {"key" : "isArchived"}}

Regardless of what setting key I use, it always returns the following error:

b'{"error":{"code":108, "message":"Internal error: Unknown setting key"}}'

Any help would be greatly appreciated.
