Can someone explain what this error is saying and where I might look to correct it? I'm at a loss in trying to figure out what I've missed in my processing. Im not finding other posts like this either.

the referenced file line- rel_cchg_dimcchg.csv, position:1234657, line:24844] does appear to be any different that the previous line.
