Can you give some examples?

As far as I know, elasticsearch 7.x no longer needs mapping type, so we don't need to fix the mapping type. I think we don't need to correct the mapping type, but delete the meaningless mapping type. Here is a discussion on mapping type.

Thanks @linuzb, some indices (slo_data, slo_trace_data_daily) get inconsistent doc type from _doc to data during upgrade from es6 to es7, not sure if this happens every time.
