The reasons the feature cannot be installed (validate), or the reasons the install failed (install). Empty when there are none; never undefined.
The message of the response, unchanged (for example Validate complete. 24 failure(s).).
The status field of the response body (200 in every response seen).
The outcome. For validate: true when the feature can be installed. For install: true when the request succeeded and the response reports no failure.
The outcome of validating or installing an IDM tenant-configuration feature, as
frodo.cloud.idmFeature.validateIdmFeatureandinstallIdmFeaturereturn it. Unlike the body the endpoint sends, which has different fields for validate and install, every field is always present, so a caller does not need to know the response shapes.
