Observed behavior

While implementing caching integration tests I needed to make changes to the flagd JSON configuration file at runtime. As such, I parsed the existing configuration file, made changes to the structure and wrote it back to the file. This results in the error "set state: invalid JSON file".

This is due to the targeting property not being valid if set to null. Marshalling the eval.Flags struct sets any empty Targeting fields to null. The solution is to add omitempty to the json tags of this field.

Expected Behavior

Marshalling eval.Flags to JSON is valid for use as configuration.
