It's expected to be an object - in case a serialized string is available to the instrumentation, the instrumentation SHOULD do the best effort to deserialize it to an object. When recorded on spans, it MAY be recorded as a JSON string if structured format is not supported and SHOULD be recorded in structured form otherwise.
