dream skin target art should serialize

Error message

dream skin target art should serialize

What it means

dream_skin_target_runtime_script serializes the dream skin art assignment to embed into the injected runtime script, and this expect-style error fires if serde_json::to_string fails. Serializing internal art data should never fail, so the error signals an internal invariant violation (e.g. a non-string map key in art config), not user error.
