Error copying rows from to : Redundant argument in printf at /usr/bin/pt-online-schema-change line 3595.
I am intermittently getting this error on some tables when running osc. The new target table is created, but after a few mins, before any progress line is displayed, this error appears during the copy data phase. I can’t find any commonality in the data of the tables that are having this problem. In testing, I’ve even tried setting all rows/columns to null, but the error still comes up.
I’m unable to find any more information on this error. Any ideas what is the root cause?
